You're right - precedence is completely ignored. The relevant syntax rules
are:
| '(' pfxExp qop ')'
| '(' qop atomic ')'
These ought to be:
| '(' exp qop ')'
| '(' qop exp ')'
but I suspect this would trip up the code that rearranges expressions
according to fixity declarations.
I've added this to the bug list but have no immediate plans to fix it.
