Exactly - anyone who has done any maintenance/enhancement work will know
what a nightmare 'var' parameters can be when trying to unravel someone
else's undocumented code. It's all very well saying 'look at the formal
list', but when you have 50 units of someone else's gunge and a week to get
something working, there is only so much distraction you can take - flitting
about between units to check the called parameters list is a PITA I could do
without. It would help if the editor/codeInsight highlighted actual var
parameters in a different colour.
