The hyphen will be interpreted as a minus sign.
If you have something like:
#declare A-B = 5;
#declare A = 1;
#declare B = 2;

Then you'll have a problem with this:

translate <A, B, A-B> been interpreted as translate<1,2,-1>

You have no way to diferensiate between A-B (the variable) and A-B (A 
minus B)


The same way, you can't use any of those in a name:
|!&*/+-.^=%"'@#\(){}[]<>
