mksh can do this with:
${ foo;}
foo runs in current shell and the ${ ... } is substituted with its
output. One more cool thing mksh has - ${|foo;} which is replaced by
the value of REPLY after running foo in current shell. I think that
each time a serious, optimized coding occurs (like when creating an
advanced theme), those will be very handy.
