An if-expression is frequently requested, and I expect people will
continue to ask for it until I add one :-)

Who (besides you) has ever asked for generalized quantifiers?  They
were in ABC, with slightly different syntax: 

  >>> IF EACH x IN {3; 6; 9} HAS x mod 3 = 0: WRITE "Yes"
  Yes
  >>>

But they weren't useful enough IMO to bother incorporating at the
time.
