esvect and reflectbox

[Tom Jones]

Hi,

I am trying to create a leftarrow of \vv{}. I thought I could just
reflect the vector, but the solution has escaped me. Could someone help
me out?

\def\traitfill@#1#2#3#4{%
$\m@th\mkern2mu\relax#4#1\mkern-1.5mu%
\cleaders\hbox{$#4\mkern0mu#2\mkern0mu$}\hfill%
\mkern-1.5mu#3$%
}

was replaced with

\def\traitfill@#1#2#3#4{%
\reflectbox{$\m@th\mkern2mu\relax#4#1\mkern-1.5mu%
\cleaders\hbox{$#4\mkern0mu#2\mkern0mu$}\hfill%
\mkern-1.5mu#3$}%
}

But the result is incorrect (the vector does not fill properly).

Thanks.
