How can you tell when the exponent has ended? At least for complex 
arguments, the next thing after the exponent will be the mantissa of the 
next number, which could look exactly like a decimal number, so it's not 
enough to just check for a non-digit character.
(If the next thing was an Lname, there'd also be consecutive ASCII 
digits, but that seems to be impossible, so maybe complex numbers are 
the only problem case).
