As a further refinement, one could reduce the “overhead" down
to a single function call in the IF itself:
IF Out.Debug() THEN … debug code … END
IF debug THEN … debug code … END
Of course, the debug code is still sitting there, as are the strings
used by it, but it is never executed if Out.Debug() returns FALSE;
which one can achieve by replacing the (dynamically-loaded)
Out module with a stub version in production..
The purist will of course not be satisfied with all these
shenanigans discussed here.
Apart from compiler directives (which one can have different
opinions about - see Tony Hoare’s comment), I don’t know
of any truly satisfactory and/or “clean” solution to this.
