Re^2: Should chomping a constant always raise an error?by BrowserUk (Patriarch)

That would require anyone calling the sub to tie the constants--which makes no sense at all.
It just took me by surprise that chomp died when asked to inspect a variable that was readonly. The work-arounds are myriad:
But, as chomp has to determine if there is anything to chomp, before attempting to modify it's argument, I just expected it to make that determination before checking for readonlyness. It doesn't do it that way, so I have to do extra tests or copies myself.
I've gotten spoiled by Perl's DWIMming things like negative offsets don't die, they work backwards from the end. Same with negative subscripts; ranges that produce no values; empty lists that act correctly regardless of the context etc.
On this occasion it didn't DWIM for me.
