That is not a subref. `perl -E ' say ${\"FFF"}' FFF` [download] All you are doing is referencing then de-referencing the returned value of the sub. It is just a way to call a sub inside quotes - but I dislike the obfuscation it causes. All power corrupts, but we need electricity.	[reply] [d/l]

Ah, I see. Well, the real answer is that I left it like that because I was playing around, and I agree that it’s unnecessary. Also, I thought it was a subref. Anyway, thanks for your help!	[reply]
