Hey,

Alrighty. Say we have: 
my %inst = (
    "unimp" => "\e[31munimp\e[0m",

    "be" => "\e[31mbe\e[0m",
    "bne" => "\e[31mbne\e[0m",
    "ba" => "\e[31mba\e[0m",
    "bl" => "\e[31mbl\e[0m",
    "call" => "\e[31mcall\e[0m",
    "jmp" => "\e[31mjmp\e[0m",
);

And Im using it like so: 
s/(^.*<)\:([a-z]+)>/$1$inst{$2}/;

Now, this all works fine as long as the found variable, $2, exists as a key in the hash. I was wondering if anyone here have some neat way of making it possible to add some kind of "default" key in the hash (without having some kind of function ofcource, that checks). Something like: 
    "default" => "\e[31m$the_key\e[0m",

[download]
So, the "default" is used if nothing else matches... Yes, a function can be used, but I thought there must be some cool perlish way doing this! ;)

Thanks,
Ace
