Actually that avoids many tricky problems in the compiler 
implementation.
When an inline metaprogram can add declarations that requires the 
compiler to have support for deferred and partial symbol 
resolution.

At least if you want it work consistently. Static if, works in 
most cases that I've seen it used... But then again a case that 
didn't work wouldn't end up in production code so it's hard to 
tell. When you start playing around with it a bit you'll find it 
can have very bizarre behavior.
