why does Perl choke here?

[Z. M. Wu]

Perl does not like if $other contains special characters
like * ] in the following

my @a=split/$other/,$req;


My current workaround is

$other=~ s/[\)\(\*]/_/g;
$req=~ s/[\)\(\*]/_/g;

before the split.

Any insight or better solution would be helpful

Thanks

No, they are special characters in regular expressions, and need to be
escaped.

My current workaround is

$other=~ s/[\)\(\*]/_/g;
$req=~ s/[\)\(\*]/_/g;

before the split.

Better solution:

my @a = split /\Q$other/, $req;
