For some reason, I find those almost impossible to read.

We have constant-propagation in the compiler (or can assume we do); and we
have overloading of functions. So the following could behave like a literal:

  $a = num( radix=>256, digits => [ [0xff, 0b11111111] , [255, 0c377] ],
exponent => 2<<16 );

  assert( $a == 0xffffffff );

Anyone who wants to do something that nasty shouldn't care that it looks
like a function call. Its a very rare thing to do, so it doesn't need
special syntax.
