Is there a way of expressing integer literals in anything other than
decimal, without doing overly complicated type conversions?

Here are a few ways to express the number 16

16#10#
2#10000#

The number before the first # is the radix that you're using, the
numbers between the two ## is the number you're trying to represent.

KJ is correct. I might add that the radix is always expressed in
decimal. It would be rather confusing (but simple to write!) to have
the radix expressed in the same base as the number (always "10")

Not to mention impossible to implement... think about it...

That's what I meant by '(always "10")'

Not all things simple to write are easy (or even possible) to
implement.
