That was my hope. I'm sure there is *some* speedup, but it wasn't visible
in 30 second runs, with granularity 1 second. I think the main jump-table
overhead overwhelms the difference between 'add1' and 'psh1; add'.

Er, PRS?

Just about anything that tokenizes. My 'QValue_t' (don't ask about the
'Q' - its historic) is just a union like that. I cheat and store the
type as the top 6 bits of the values. All values are DB references, other
than 'int' and 'fixed', which I cheat on. That causes my limit of 64 million
database entities.

Definitely interesting. It had never occurred to me that C++ won't let
you have a union of classes, but it sortof makes sense to me.

But with inlining and heavy optimization, even that might go away.

Er, doncha need some 'break's in there? That's my type of bug!
Plus, you are answering my question with another one. What's the syntax:
new(<field-name>) <typename>
do!!? Treat me as completely C++ illiterate. This is likely too basic for
the list, so feel free to educate me privately.

The rest I followed - a fascinating look at higher level ways of doing
things.

Me neither! For instance, I absolutely do not know that that can stomp the
return address, resulting in the program branching off into the middle of
some other unsuspecting routine.

Don't design inefficiency in - it'll happen in the implementation.
