Re: duplicated local variables with same name

Yeah, that's why I mentioned Go. you can do

foo := 25

foo := "I'm a foo!"

foo = 25 // ERROR! foo is type string!

Would you expect an error? Perhaps you don't actually know C, if you're steeped in awesome things like Lua and Erlang, but this totally valid C. In fact, it outputs what you would expect, if you were familiar with Lua local scoping with blocks:

    foo == 100

    foo == 25

You can't redefine a var in the same scope like you can with Lua or say Go's := operator, but you can definitely redefine variables within a scope in lots of languages.

But I think that’s not the point. In C what you CANNOT do is:

int foo = 25;

int foo = 25;

.. but you CAN do something similar to this in Lua.
