Comment(by wjp):
Conversions between {{{BooleanPolynomialRings}}} use name-based semantics
rather than index-based ones like other polynomial rings:
{{{
sage: R.<x,y> = BooleanPolynomialRing()
sage: S.<z,x> = BooleanPolynomialRing()
sage: R(S.0)
*kaboom*
}}}
{{{
sage: R.<x,y> = ZZ[]
sage: S.<z,x> = ZZ[]
sage: R(S.0)
x
}}}
