Bug in math arrows

Bug in math arrows

[Aditya Mahajan]

Hi,

There is a bug in extensible arrows. The syntax of extensible arrows is:

\xleftarrow{below}{top}

but when the optional argument is used

\xleftarrow[small]{A}{B}

then A ends up on the top and B on the bottom.

Thanks,
Aditya

The "x" commands change the position of both texts and when you change
the instance for the command the reversed order is overwritten (search for
the order key in math-stc.mkvi).

\starttext

$\xleftarrow{A}{B}$

$\mleftarrow{A}{B}$

\stoptext

I would still consider it a bug :-) Either order is fine but it should be 
used consistently.
