Re: Use of SWITCH vs IF ELSE in speed and readability

in reply to Use of SWITCH vs IF ELSE in speed and readability

Another approach is to use a dispatch table - a hash of code references,

my $dtbl = {
    1 => sub { $abc = 1 },
    2 => sub { $def = 1 },
    3 => sub { $xyz = 1 },
};

exists $dtbl->{$x} ? $dtbl->{$x}() : $nothing = 1;

Just a style difference, but I really dislike using the ternary `? :` for statements (code which is of irrelevant or void context, performed for their side-effects). It's all just code and doesn't matter inside the machine, but to me, the ternary is intended to express a selection of either one expression or the other. -- `[ e d @ h a l l e y . c c ]`	[reply] [d/l]
