: Ouch.  You just created a list of the keys in %ENV for no good
: reason.  Why not do:
: 
:   map { ... } map { [ $_ => $ENV{$_} ] } keys %ENV;

Point taken,

: if you're going to use keys %ENV.  Or, use it in the scalar context:
: 
:   map { ... } map { [ each %ENV ] } 1 .. keys %ENV;
: 
: But map() in void context is evil. ;)

I know, that's why I like his better.  Besides, I said it was
*something* like that. :)

I like to do simple processing of hashes/lists in one (visualy
one) operation.  So, I now have a better way to do that :)
