Sometimes match seems like overkill for something like matching
coefficients between equivalent expressions of an expression, e.g.
the equation of a circle: (x-xc)**2 + (y-yc)**2 - r**2 = 0 and
the general polynomial a*x**2 + b*x + c*y**2 + d*y + e*x*y + f = 0
Are there any thoughts about adding something that would behave like
this:
>>> from sympy.abc import a,b,c,d,e,f,g,x,y
>>> eq = x**2+(y-3)**2 - 5
>>> pat = a*x**2+b*x+c+d*y**2+e*y
>>> print print match_coefficients(eq, pat, x, y)
{e: -6, a: 1, b: 0, c: 4, d: 1}
