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

Q: Is there a better way?
The above implies the format is something like:
SNEEXADMINEND
in which case, suicide is an honorable option.
Adding in some sort of delimiter:
SNEEX|ADMIN|END
and then you can just split
suicide is an honorable option.

SNEEX|ADMIN|END

SNEEX = \foo,

$x is going to be zero for all of them, because $_ does not contain any

The /i penalty had nothing to do with backtracking, but with making an
extra copy of the target string. If the target string was short, it wasn't
really much of an issue. It's described on p278.
Once the book came out, it (and many other bugs) were fixed
$c = grep {/[osx]/i} @_;
Is there a better way?

Given:

$c = grep {/[osx]/i} @_;
Regardless, the {} there is redundant and actually slows you down a
bit (Perl has
element which isn't
cheap and its not smart enough to optimize it out.
But you can't just take them off since you'd need to put a comma in
then:
$c = grep /[osx]/i, @_;
or perhaps even
$c = grep /[osxOSX]/, @_;
