Nice list! CMake is missing a few dozen entries though!

"Stringly typed" - even lists are just semicolon-separated strings.

Insane quoting rules. I recently tried to work out exactly how the argument parsing works and the source code has undocumented behaviour. It's ridiculous.

Accessing undeclared variables works fine. They're just empty. Good luck tracking down silently ignored typos!

Scratching the surface...
