Since Forth200x, the number #0 would be recognised as zero; there are
numeric prefixes such as # for decimal, $ for hex and so on. So this

hex
#10
decimal .

should print 10, not 16. But this

: #20 ." twenty" ;
#20

should print twenty, not put 20 on the stack. The dictionary is searched
beofre attempting conversion to a number in a standard forth, and your
method is not standard. You either meet the requirements of the standard
in this area 100% or 0%; there's no nearly. As my grandmother used to
say, nearly a hit is still a miss.
