Note the backslash before prec in the macro body has to be escaped with
another backslash. I inverted the nesting of the macro and conditional
here.
Aha :)
Note also that you can't do @macro prec because @prec is already
defined as a control sequence.
Ah..
The "@tex" and "@end tex" lines have to be on lines by themselves. Any
backslashes in a macro body should be doubled, as well.
Just adding newline to make that happen seems to break the inline format
macro. So..
a @precb{} b
Seems to do the trick, just /one/ little issue is that it doesn't seem to
allow you to format the whole thing as math in one go, e.g.:
@math{a @precb{} b}
Makes stuff unhappy.
Is there a way to make that work?
Thanks very much! :)
