New description:
The `ModularForms` command has some slightly counter-intuitive behaviour
on some types of input:
{{{
sage: ModularForms(gp(1),12)
---------------------------------------------------------------------------
TypeError
[much snipped error message]
TypeError: Error executing code in GP/PARI:
CODE:
sage[4]=level(sage[3]);
GP/PARI ERROR:
*** expected character: ',' instead of: sage[4]=level(sage[3]);
^-----
}}}
I realize that this is because the first element is supposed to be a
group, although a (Sage) integer is allowed.
Would there be any support for having an if statement in the function to
catch magma or pari elements and transform them into their Sage
equivalents?
