\def\xrightarrow{\doifnextcharelse[\noxrightarrow\doxrightarrow} \def\xleftarrow {\doifnextcharelse[\noxleftarrow\doxleftarrow} \def\doxrightarrow{\dodoublegroupempty\dodoxrightarrow} \def\doxleftarrow {\dodoublegroupempty\dodoxleftarrow } \def\noxrightarrow[#1]{\dodoublegroupempty\dodoxrightarrow{#1}} \def\noxleftarrow [#1]{\dodoublegroupempty\dodoxleftarrow {#1}} which accepts \xrightarrow{x}{y} \xrightarrow{x} \xrightarrow{}{y} \xrightarrow[x]{y} etc, actyally, we should then also accept \xrightarrow[x][y] but more interesting is to use the optional arg for tuning purposes \if0#1\else\mkern#1mu\fi test, does a \mkern0mu hurt? > > Will make copy paste a bit easier!
