Comment(by benjaminfjones):
I see your point. How about the following names:
* `exp_integral_e`
* `exp_integral_e1`
* `exp_integral_ei`
* `log_integral` (for li)
* `log_integral_offset` for (Li)
* `cos_integral`
* `sin_integral`
* `sinh_integral`
* `cosh_integral`
... and maybe aliases for the usual mathematical names: `li, Li, En, Ei,
E1, si, ci, shi, chi` ? Perhaps that would be too many new names in the
global name space?
