>\def\longrightarrow{{\relbar\joinrel\rightarrow}} Nice try, but no cigar. TeX's braces have the `unusual' side-effect of turning their contents into a mathord! Compare: $$X{\relbar\joinrel\rightarrow}Y$$ with $$X \relbar\joinrel\rightarrow Y$$. Oh dear... Really the culprit is the fact that there's no way to bracket an argument in math mode without simultaneously turning it into a mathord. Alan.
