[doc] Add (ord) example to map() document

[jidanni]

Where

perlfinc
Description

perldoc -f map

shows

 my @chars = map(chr, @numbers);

Maybe this also could be mentioned:

$ perl -wle 'for(qw/A B C/){print map((ord)-64,$_)};'
1
2
3

Or maybe something like it is mentioned already.

Why should this be mentioned? I'm not seeing it.

Why should this be mentioned? I'm not seeing it.

I, too, do not see what value the suggested edit would add to our documentation.
