New description:

 Evidently:
 {{{
 sage: R.<x,y,z>=QQ[]
 sage: f=x^2+3*y
 sage: magma(f).sage()
 NameError: name 'x' is not defined

 apply [attachment:trac_11580-magma.patch] to extcode repository. Apply
 [attachment:trac_11580-doctests.patch] to the sage library.

Comment:

 Rebased on top of #11456.

 Removed the function {{{"intrinsic Sage(X::SeqEnum) -> MonStgElt,
 BoolElt"}}}, because it was equal (modulo documentation) to the one in
 #11456.
