If you really want to go over the top:

\startMPextensions
vardef math_stacker_arrow_shape =

drawarrow

bottomenlarged (OverlayOffset/2) topenlarged (OverlayOffset/2) ;
)
enddef ;
vardef math_stacker_leftarrow_shape =
math_stacker_arrow_shape
enddef ;
vardef math_stacker_rightarrow_shape =
math_stacker_arrow_shape rotated 180
enddef ;
\stopMPextensions
\startuniqueMPgraphic{math:stacker:\number"2190}
math_stacker_draw(math_stacker_leftarrow_shape) ;
