I don't think your comment syntax should be aded. Nim has a Pythonesque style
it should just keep it. Its not what you add, its what you don't add makes a
great language.
I also don't agree with / / it should just be a C like system with / / and / *
... * / and / * * ... * / not some thing unfamiliar.
I also feel that syntax is not that important, its the C inter-op, type system
and the operator overloading, and speed which makes me excited about nim. The
language would have been fine with C like if(){} / * ... * / syntax but it
choose the python's if : # syntax and that just small layer to the language.
