Re^3: How to match a ;

I'm puzzled as to why you switched to double quotes and then had to escape the backslash in your third pattern. Sticking to single quotes or using qw{ ... } would have obviated that need.

$ perl -le '
> $line = qq{;\n};
> print
>    $line =~ m{$_}
>    ? q{}
>    : q{no },
>    qq{match $_}
>    for q{^;$}, q{^;}, q{^;\z};'
match ^;$
match ^;
no match ^;\z
$ perl -le '
$line = qq{;\n};
print
   $line =~ m{$_}
   ? q{}
   : q{no },
   qq{match $_}
   for qw{ ^;$ ^; ^;\z };'
match ^;$
match ^;
no match ^;\z
$

In some places I like DWIM, in other contexts I like to be explicit. In this case I thought being explicit about how the \ gets handled was probably a good thing™. Perl's payment curve coincides with its learning curve.	[reply]
