Often I feel like there is a barrier between your thoughts and their execution which does not exist in Python or Ruby for example. When I switch from OCaml to Python it's like a breath of fresh air.
In conclusion I think common tasks must be syntactically abstractable. For example, I find working with standard data structures in OCaml annoying, as if I were programming in C. There are tons of syntax extensions for OCaml that try to fix these defects, but it only supports my claims.
