The syntax can be made identical (even better) than that of amsmath.

\def\xleftarrow {\dosingleempty\doxleftarrow}

Will make copy paste a bit easier! Though these days I find myself
writing more in context and soon will face the reverse problem. I will
need to copy context math into latex (needed for final journal
submission) and some of the math features are simply missing from
latex :)
