I wonder if you could take a look at this old pull request:

My feeling is drop this but I thought you might offer a perspective
after your summer project.
Background: the symbolic package inherited a bunch of code from the
specfun pkg. This included "sinint" and "cosint" implementations.
They were not very good so I replaced them [1] with rather slow,
nonvectorized calls to the SymPy (ultimately the arbitrary precision
python library "mpmath"). The PR is the original specfun code, with
a few failing tests added by me.

I'm sorry, wrong person!
*Michele*, I meant to refer the above to you!
