in reply to Relative Merits of References
Since almost all hashes and arrays I make end up getting passed to
subroutines, I usually just create them as refs. This has the
(slight) benefit having a consistent point of dereference in mainline
code and subroutine code instead of having to remember to move the
arrow around. Also foo($this) looks nicer that foo(\%that).
RefFoo
#!/usr/bin/perl use strict; my %rgbs = ( yellow => { r => 0xff, b => 0, g => 0xff, }, magenta => { r => 0xff, b => 0xff, g => 0, }, ); print "$rgbs{yellow}->{r}\n"; foo(\%rgbs); sub foo { my $rgbs = shift; print "$rgbs->{yellow}{r}\n"; }
