Here's an idea that would be convenient for future implementations of Solve
Suppose v,w are vectors, a,b are points, and we want to know k,l
scalars so that the following equation holds:
v k + a = w l + b
It's a bit irksome that I can't give the equation to Solve just like
this, instead I have to define a transformation rule:
Solve[
v k + a = w l + b /. {x_,y_}=={w_,z_}:>{x==w,y==z} ,
{ k, l} ]
