I guess you could do the FP thing: 

sub oddEls; sub oddEls{ @_ ? (( shift, shift )[ 0 ], oddEls @_) : () }

print oddEls 'aaabbcddddaee' =~ /((.)\2*)/g;;
aaa bb c dddd a ee

"Science is about questioning the status quo. Questioning authority".
The "good enough" maybe good enough for the now, and perfection maybe unobtainable, but that should not preclude us from striving for perfection, when time, circumstance or desire allow.
