We use functions heavily - having an include for each project with up an over a hundred deffun's - and I only have two issues/complaints with them.
First the need to have deffuns and second, the spurious warning messages we get at compile time for internal returns not having a return value .
I mean they don't return anything and IMNSHO shouldn't
have one. ( We use return (dum) as a workaround )

This causes me to think of the complement to subs and that is functions. Functions are quite useful in VB (et al) yet don't show up at all in legacy code and don't get that much airtime here on this forum. I've only ran into them once on UD when hooking into Redback. Every time I write a SUB that really is a function in purpose, I tend to name it GET.PRICE or GET.USER or GET.PRINTER etc.
So are functions a kept secret in MV programming or has no-one had any issues with them? I'd like to know so I could either get better with them or ignore them and continue with subs.
