Hello,

I have the following macro to aid in presenting calculations in
solutions to coursework questions etc. for my teaching:

#+macro: calculate src_calc[:exports code]{$1} =3D @@latex:\fbox{@@ src_ema=
cs-lisp{(setq var-$2 (string-to-number (calc-eval "evalv($1)")))} \to $2 @@=
latex:}\\@@

The "\to" which org catches and converts to =E2=86=92 on export causes a pr=
oblem
with font-locking:

Error during redisplay: (jit-lock-function 1) signaled (wrong-type-argument=
 vectorp =E2=86=92)

Using math mode directly, i.e. \(\to\) works just fine, at least for
LaTeX export, but I thought I'd mention this anomaly in case it bites
anybody else!

thanks,
eric
