Does this affect anything that could be testable or is it just for consistency?

[edgarcosta]

It enables something like:

showgood(lambda : acb_series([arb.pi(), (arb.pi() + arb("1e-100")).sin()]), maxprec=10**3)
3.14159265358979 + (-1.00000000000000e-100)*x + O(x^10)

before you would have to use:

showgood(lambda : acb_series([arb.pi(), (arb.pi() + arb("1e-100")).sin()]).coeffs(), maxprec=10**3)
[3.14159265358979, -1.00000000000000e-100]

otherwise you would trigger:

raise TypeError("must have arb or acb")

[edgarcosta]

Here is a more realistic example:

>>> from flint import *
>>> z = acb(1+1j); tau = acb(1.25+3j)
>>> showgood(lambda: acb_mat([[tau]]).theta(acb_mat([[z]])).transpose(), dps=25)

Okay, I see. Looks good!
