Dear Mathé,
From a quick skim of
https://github.com/mathehertogh/adeles it looks very impressive. I
do not know if it is better to incorporate the code into Sage or
leave it as a stand-alone package, but in case the code does live
in its own
alize as in
SR). One more reason is that the numerator/denominator methods are used
for more complicated mathematical objects in Sage, where calling them
with arguments is sensible. In the python-ideas discussion Vincent
Delecroix mentions that also real and imag methods/properties have the
arguments, or using nullable
types when there is a certificate argument, and so on.
