Comment (by SimonKing):
I think a straight forward way out is to use the correct variable name for
internal representation.
With the commits that I am now testing, one would get
{{{
sage: K.<t> = FunctionField(QQ)
sage: R.<x> = QQ[]
sage: M.<z> = K.extension(x^7-x-t)
sage: M(x) # I guess this is important for backwards compatibility
z
sage: M('z')
z
sage: M('x')
Traceback (most recent call last):
...
TypeError: unable to convert string
}}}
But before pushing, I need to run tests...
