Wow, that's a lot of machinery to avoid running :s/\\d/[0-9]/gc in your editor. I think I'll always choose to avoid the recurring cost.

And I'm mostly not talking about CPU cost (but I suspect that is non-trivial), but the cost of things like mentally having to track new rules about how changing m// to s/// or split() requires extra attention, having to track that \d means different things in different places, having to search for pragmas each time I see \d inside m// if I care which meaning it has, the risk of having to debug the chain of code required to support this, etc.

The risk of just wasting time because of a bug in the added pile of code required to support this is my biggest concern (after having repeatedly been burned by such things), especially when I consider the risk of this idea of pretending \d isn't \d getting in the way of some other tricky module's reasonable-sounding assumptions.

Just because something is possible doesn't mean it is a good idea. :)

The second version, which uses overloading, should work with `s///` and `split //`. `perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'`	[reply] [d/l] [select]
