newLISP v.10.3.0 on Linux IPv4/6, execute 'newlisp -h' for more info.

This is fixed here:

There will be a maintenance release later. This bug stayed undetected since 10.2.

Hi Lutz,
It took some time to discover that my functions where all returning 'true ;-)
..to this (++) issue.. quite funny actualy but not consistant, thats how i discovered it. Thanks for the quick fix!
The main difference now between (++) and (inc) is integer and float handling, could then (++) and (--) be
handled like (inc) and (dec) too? Just to takeaway confusion on the function format ?
Example from 10.3.1 ->
> (++)
ERR: invalid parameter in function ++
> (inc)
