I'd opt for argexpr="'''src="food(%d,%d)"''' % (3,4)" so it would be
generic enough to use for any weird arg you may need to write, as cusomt
onclicks are common for me.  Unless the parsse can be written in such a
way that an al- pre fix is picked up like Andrew write.  Though al-
there might be confusing, I'd go with either: anything ending in expr or
(my preference) anything leading with an underscore:

	_src="'foo(%d,&d)' % (3,4)"
