Re^3: 'block' idiom needed

Well yes... but then you just said return $setting outside of the braces. It'd be better for locality to not escape the braces just to get to the return and instead just do the return directly.

ah. sorry for the confusion. This is a VASTLY simplified section of code. in practice its more like: `sub configure { my $setting_a= undef; my $setting_b= undef; { run a bunch of things setting combinations of a or b , last } do someting with settings a and b }` [download] there are too many sub vars needed in the block to have that stuff in a seperate sub without passing tons of args around -- so i wanted to localize them in a breakable block	[reply] [d/l]
