in reply to C pre-processor in Perl

#!/usr/bin/perl -P
#define FOO bar
print "FOO\n";
print qq(FOO\n);

[download]
prints 
FOO
bar

[download]
and that's reason enough for me to avoid it.

    Well, that doesn't work with the constant pragma either. Back to globals...

      I think you missed the point that code makes. Whether or not a constant define'd via preprocessing is replaced inside a quoted string depends on the quoting mechanism used. It isn't replaced with actual quotes ("" or '') but it is with the generic quote operators¹ q() and qq().

      So, change how you quote your literals and you might end up changing the literals themselves. I don't like things that change unexpectedly like that.

      1. This is, of course, because it is a C preprocessor and not a Perl preprocessor.
