Dear monks,

I wrote for my current client some code that looks like this:

sub MySub
{
    ...some stuff...
    return map split(/ /,$_,2), map uc, @somearray;
}
[download]

I like it a lot (I know, I could even leave out the "return"). However, in a few months I'll be off to new challenges and I will have to leave this code to be maintained by somebody else.
Should I let my pride prevail and leave the code as it is, our should I be merciful to the maintainer and refactor it to something more readable to the non-initiated?
