Lots of people (like me, though I'm often told I'm a unique
snowflake and nobody programs like me) debug code by editting
the source code to enable/disable debug code rather than
messing with the makefile.
Take a look at about any source file in dmd, for example, with
the commented out printf's, and template.c, with the file scope
#define LOG 0.
D needs to support this style of debugging, and the 'debug'
conditional with how it is set is just the ticket. The feature
works as designed and intended.
I can understand that, but it does seem a bit risky in this case.
The suggestion of creating a warning for it seems like a good
one, since it allows you to debug like that but needles you to
not leave it that way.
