Re^3: Tail recursion elimination

jdporter,
Right - when you re-use the stack frame it is an optimization referred to as elimination. When you don't re-use the stack frame but create a new one, is it still called elimination? Perhaps that is too pedantic.

jdporter Isn't that the same thing? in a stack discipline re-using a stack frame just means popping a frame and then pushing one. Bill H `perl -e 'print sub { "Hello @{[shift]}!\n" }->("World")'` [download]	[reply] [d/l]

Um, goto &SUB does create a new stack frame, but only after the old one is stripped off. (Shouldn't leak memory though.)	[reply]

Anonymous Monk, Ok - you have copied/pasted from the same node I have linked to twice now. What exactly is it that you think I am missing? Cheers - L~R	[reply]
