Hello!

Mathematica lets me define functions which have their parameters in
subscripts, e.g.

In[16]:=
\!\(foo\_\(k_, l_\) = k l\)

In[17]:=
\!\(foo\_\(3, 4\)\)

Out[17]=
12

My question is, how can such a function be defined in a package and made
available to the outside. Any variations of foo::usage I could come up
with did not seem to do the job.

Thanks for suggestions,

   Henrik Weimer
