In fact, I find that \dfrac{} creates unsightly leading space and that

It seems that displaystyle fractions insert extra vertical space before the
main item.
With textstyle fractions, the code works fine.
\blank[back,overlay] can get rid of the gap above the first row, but not
the space inserted by \dfrac.

Something is wrong in the current implmentation of \tfrac.
If we take away all the bells and whistles provided by
\definemathfraction,
* \tfrac#1#2 should be equal to {\textstyle #2 \over #1}
* \dfrac#1#2 should be equal to {\displaystyle #2 \over #1}
* \frac should be equal to \tfrac
Hi Wolfgang,
Thank you for these three solutions. One thing I'm missing is the role

\dfrac{\,\dfrac{9+3x-2x^2}{x^2-16}\,}

Changing it to \dfrac makes the input compile ok, but
typesets the cases in an ugly manner with really narrow

(Yes.)

Yup, I just changed a couple of things and now we have a

Hello Giuseppe,
I'm having a little trouble with the cases in amsl.
Compiling this:
\[
f(x) =

\stopcases
\]
results in an error around the \frac. Changing it to \dfrac makes the
