You know, there are contexts where this is the right answer. Like, if you
manipulate them as input/output objects and need to check the datastream
to see if the tokenising input should end.

And, the difference between Hex 0F and Decimal 15 is that both have exactly
the same bit-pattern in memory. Strangely, if you add 2 apples in hex
and 2 oranges in decimal OR octal, you still have 4 bits of fruit. So, you 
can do mixed-base sums after all. Why don't they teach you that at
school any more?

I had a chum who'd had a 6th finger cut off early. If they'd left it on, would
he have had any advantages doing finger arithmetic?

Should'a employed him then. Anybody slavish enough to dress up to get a job
is probably going to work hard for the first 7 months until disallusionment
sets in.

I still writhe with embarrassment recalling an interview for the UK N.E.R.C
to get a junior progroid job onboard the antarctic ships, when asked to
write a solution to pythagoras in pascal, there, in front of the panel. Flop
sweat and memory loss and nicotine withdrawal and sheer fright combined to
make it both humiliating for me, and revealing for them. I think they made
the right decision to quietly let me go. Still, I got to see the steam loco
graveyard at barry island so it wasn't all wasted.

PS I suspect that in this niche, people aren't working as a result of a
successful interview. I think they probably know people who know people
who trust people who let them on board. If there is an interview, its
more like dogs sniffing each other, or 'do you wanna be in my gang?' than
joining the army.
