I'm trying to use the conditional expression in a function and get the following
error message:
Parse Error: Expected 'operator', ? found instead
Here's my function:
#local ScoreStone = function(x) { (x=1) ? white_stone : black_stone }
What am I doing wrong? I thought ? was an operator -- that's what the docs say.
It happens on Windows with both 3.7 beta 28 and 3.6 as well as on Unix with
3.6. Thanks!

The syntax inside functions is different from that of the main SDL. It
doesn't have "?" but it does have "select".

I ended up making a macro instead of a function.
'white_stone' is 'stone(1, 1, 1)' and 'black_stone' is 'stone(0, 0, 0)' so I
have this which works:
#macro ScoreStone(i)
stone(i ? 1 : 0, i ? 1 : 0, i ? 1 : 0)
#end // macro ScoreStone(i)
It's kinda ugly, but it definitely works.
Thank you for the pointer to select() -- I will use that in the future.

I have since changed this to:
#macro ScoreStone(i)
stone(i, i, i)
#end // macro ScoreStone(i)
as i is either 0 or 1. Whee. Thank you again. :-P :-)

Your final solution does have an advantage, beside simplicity: you are no longer
limited to only white or black, you can now have any shade of gray.
