Please, no. The use of closed form rather than open form IF statements
is one of the things Ada (and by inheritance PLPGSQL) got right.

Frankly, I find this whole proposal, and all the suggested alternatives,
somewhat ill-conceived. PLPGSQL is a wordy language. If you want
something more terse, use something else. Adding these sorts of
syntactic sugar warts onto the language doesn't seem like a terribly
good way to proceed.
