if-let* would be nice
I could use an
if-let* macro. Wondering why there wasn't one already, I found that somebody tried to contribute it back in 2012, there was some question as to what should be bound in the else form, and then it seemed to die (https://email@example.com/msg00493.html)
I could make a pull request for this, but before I do, wanted to check if there is some reason it hasn't been done...
