Issue with @parameter

Mojo
1

Please help me fix this code:

@parameter
if False:
    comptime s = "Hello"
else:
    comptime s = "World"

fn main():
    print(s)

Error:

error: use of unknown declaration 's'
    print(s)
          ^

Interestingly, the following works on current nightly:

comptime s =  "Hello" if False else "World"

fn main():
    print(s)

ASM generation compiler returned: 0
Execution build compiler returned: 0
Program returned: 0
World

Yea, that’s roughly control flow vs just a expression.

The “if else” approach is the right approach. @parameter if isn’t like a #ifdef in that removed by a preprocessor. It has proper scoping.
