I found myself writing a application where I wanted to make a decision
based on characters at the END of a string. I wanted something like match
but working from the end rather than the beginning of the string. What I
chose by way of implementation was the following:
nekot := reverse(token)
if match("." | ")." | "\"." | ")\".", nekot) ...
I have two questions. In general is there a better way to do this? The
strings I wanted to test for are different sizes so a fixed range didn't work.
Second, could I have used
if match("." | ")." | "\"." | ")\".", reverse(token))
directly without having the reverse(...) evaluated multiple times? (An
admittedly lazy question on my part, since I could have tested this.)
