But that means pressing the shift key for the 'D', '(', ')'
and 'P' characters.  You answer doesn't address your first
complaint.


Do you prefer Ruby's parens free call syntax?  Or is it
that from practice you no longer consider '(', ')' and ':'
to be noisy?


def symbolP x
   return x>0
end

if symbolP 5 then
   print "Positive!\n"
end

   contains less noise than

def symbolP(x):
   return x > 0

if symbolP(5):
   print "Positive!"
