The '#' has a nice connotation for anyone who's used to C/C++, given
that those statements are handled at "compile time." The problem, of
course, is that they're really nothing like C preprocessor statements.
They have a different syntax, and completely different capabilities.
What's more, you can't mix them across statements/expressions, so I
suspect it would just cause more confusion.
Additionally, there's this:
#endif
Unless you plan on moving all control structures to BASIC/pascal style,
I don't think it's wise to start mixing them all over the place.
All good reasons, but there is one more:
If you use #if in the standard D language, then it'll make it harder to
use a real C preprocessor when you need it. D has support for #line in
the language so that the compiler gives you error messages relative to
the right included file and line in a preprocessor output. D doesn't
have a preprocessor built-in, and doesn't recommand using one either,
but it has support for it. Introducing #if in the D language would
break that support.
I do like the idea of a "scopeless block" syntax in theory, though it's
not something that's really been an issue for me.
Me neither.
