Re2: Inlining method/function calls?

That is very cool! Right after I ran that snippet, I looked in 3rd Camel to see what it says, but it's quite sparse in what you can do. What is possible? Where could I go for more info, especially examples ...

The -P flag turns loose the C preprocessor on your source before perl ever sees it. Its behavior is determined by the C standard, at least for the portable parts. The handiest source of information is probably a C primer. In short, the C preprocessor makes direct textual substitution. with some logic available. I've never needed it for perl, but potentially useful constructs include, `#include "filename"` - inclusion of source from another file. `#define foo some string or other` - substitution macro definition `#if, #elseif, #else,` and friends allow for conditional inclusion of source. None of this is really necessary to perl. After Compline, Zaxo	[reply] [d/l] [select]

#define foo some string or other - substitution macro definition
