Re^3: better way to convert a string into an array and an hash

[Rhose]

I'm not a golfer, but...

tr/:/,/;%h=eval;@a=keys%h;

Update

y/:/,/;%h=eval;@a=keys%h;

Update 2

If the ordering of @a is important, how about

@a=/(\d+):/g;y/:/,/;%h=eval;

[dragonchild]

This doesn't preserve the order of the keys. That's a problem.
