------------------------------+---------------------------------------------
With `implicit_multiplication(True)`, we can enter expressions using
spaces instead of `*` to separate multiplied subexpressions:
{{{
#!python
sage: var('x, y, z')
sage: implicit_multiplication(True)
sage: 3 x^4 y + 2 z sin(x z 3 y) - 3 y^2
3*x^4*y - 3*y^2 + 2*z*sin(3*x*y*z)
}}}
This works similarly for polynomials.
But it's not yet possible to set an option so that Sage automatically
postparses the output to multiply implicitly. For example,
{{{
#!python
sage: R.<a,b,c> = QQ[]; R
Multivariate Polynomial Ring in a, b, c over Rational Field
sage: implicit_multiplication_output(True) # not implemented!
sage: R.random_element()
1/7 a b - 1/4 a c - c^2 + c
}}}
Ideally, we would be able to use the output in later inputs with little or
no modification.
