Comment:
This now uncovers a regression of #12255 which was not really fixed.
{{{
File "src/sage/symbolic/expression.pyx", line 5279, in
sage.symbolic.expression.Expression.coefficients
Failed example:
f.coefficients(g)
Exception raised:
ValueError: The name "g(t)" is not a valid Python identifier.
}}}
I will now let this ticket (and with it its dependencies) lie in limbo
because, as a posting on sage-devel showed, there is no interest in
symbolic series.
