I'm reading perldoc perlref right now and under the Function Templates
section, I've come across something that's got me stumped. The code in
question is as follows...
@colors = qw(red blue green yellow orange purple violet);
for my $name (@colors) {
no strict 'refs'; # allow symbol table manipulation
*$name = *{uc $name} = sub { "<FONT COLOR='$name'>@_</FONT>" };
}
What I'd like to know is what is the purpose/meaning of the "uc" in
*{uc $name} on the second last line? I couldn't locate an explanation
for it anywhere.
Thanks in advance. :)
