Re: Re: [Myghty-users] substitution outputs nothing

[Marty M. <mar...@ly...>]

Okay, thank you very much for the information. I hope I don't sound to picky right now, but wouldn't it be better to output substitutions even if they evaluate to 0/False? Then you wouldn't have to do str(myInteger) or
myInteger |h 
for every Integer that might result to zero. Maybe that would be more intuitive (I think there are some more people who have tripped over this already).

Anyway, thanks and cheers,
Martin
