It's been awhile since I've used Pascal, and I'm not yet on the Nim bandwagon - but when I did use pascal (and I did for a few years), the case insensitivity was not, in fact, a source of surprising behaviours. I have no idea what you're talking about.

It is not really confusing that you can't have both MoveFilesEx and MoveFileSex in the same scope (and that you can refer to a variable or procedure by a either name). Nim just feels like taking this a little farther - making '_' the lower case version of no character. Not at all a big jump from Pascal, and pascal is not confusing.

In fact, experiments teaching Python to non-programmers indicated that the two biggest confusing issues were case sensitivity and integer division[0].

That sentiment is very often expressed by people coming from C/C++/Java about Python's indentation (What? Whitespace is significant to semantics? That's awful!). And you know what? I know not of one person who actually tried Python and actually had a problem.

[0] http://www.alice.org/ - can't find the rational description now; but I was following its development, and IIRC those were the two biggest stumbling blocks in Python (which were therefore changed in Alice)

This "feature" makes it just as annoying as dealing with, eg, PHP, where the same codebase may feature NULL or null. It encourages inconsistency.

Yes, because making grep (and search functions from code editors and IDEs) useless is a fantastic idea :(

I have no issue with Python's indentation (apart from the fact that reindenting badly indented Python is not fun). That's a different problem. Whitespace is a different solution, but not particularly confusing.

I feel that basing the design of a language based on the use-cases of non-programmers, for something they will likely not consider an issue after two weeks, at the expense of code maintainability is a mistake.

This is not a problem in practice, after two weeks. Seriously - Pascal has fallen out of favor, but there are large pascal codebases that demonstrate this point. NIL, NiL, nIl, nil are all accepted as the null pointer. It really isn't a problem in practice, not even remotely.

No, grep is not useless, though it isn't quite as useful (just as much as #define makes grep less potent in C/C++). nimgrep fills some of the void.

The Alice study was just an example BASIC and Pascal (and its predecessors) were designed in the late '60s and early '70s and feature case insensitivity. Nim follows Pascal, not Alica.

It looks like you are really upset with choices because of some theoretical objection. I have not really used Nim, but I have used both BASIC and Pascal very extensively. Case sensitivity and alternate spellings are NOT problems in practice, even though you try very hard to imagine that they are.

I'm not upset, I happen to think that these choices add complexity and promote inconsistency for little practical gain.

If you want to enforce a consistent style, it's one more obstacle in your way. And considering how often projects end up with little technical lead and no enforcement of style whatsoever, I'd rather avoid that.

It makes it useless to find an identifier, which means useless 90% of the time I want to use it on a codebase.

> nimgrep fills some of the void.

See? More complexity for no appreciable benefit. A much saner approach would be to implement a compiler warning for this kind of thing.
