Use a hash as a jump table, with the keys
being what you extract and the values being
subs. If the string is regex-able then
something like:
my %jumpz =
(
SNEEX => \&sneez,
...
);
...
my ($name) = $vflag =~ /\w+/;
my $sub = $jumpz{$name}
or croak "$$: bogus vflag: $vflag"
double-check the syntax, but if you feel
like shortening the result:
$jumpz{($vflag =~ /\w+/)[0]}
or
$jumpz{($vflag =~ /\w+/)[0]}->($vflag)
should return the sub or execute it on the fly.
That or a goto $jumpz{(...)[0]} should dispatch the thing
completely.
