Re: Getting Error in character class

it's the array access that's causing the problems.. this works around it:

  my $s = $imlre{$_}->[1];
  $input =~ s/<$s[^>]*>//g ;

Curlies can be used for disambiguation: `$input =~ s/<${imlre{$_}->[1]}[^>]>//g ;` [download] When dealing with HoA, HoH, AoA and AoH, the arrays are optional between the indexes. `$imlre{$_}->[1]` is the same thing as `$imlre{$_}[1]` When Perl sees `$imlre{$_}->[1][^>]` it thinks you mean `$imlre{$_}->[1]->[^>]` rather than a HoA followed by a regexp. Between the square brackets, an index is expected. Since `^>` is not a valid perl expression, you get an error. Update*: Rearranged explanation for clarity.	[reply] [d/l] [select]

$imlre{$_}->[1]
is the same thing as
$imlre{$_}[1]

When Perl sees
$imlre{$_}->[1][^>]
it thinks you mean
$imlre{$_}->[1]->[^>]
rather than a HoA followed by a regexp. Between the square brackets, an index is expected. Since ^> is not a valid perl expression, you get an error.
