In R there is a little syntactical nudge in this direction in that the matrix inversion function is actually called `solve`. `solve(A, B)` gives you the solution to AX = B, and B's default argument is the identity, so `solve(A)` just gives you the inverse, and any instances of `solve(A) %*% B` in your code should stand out as red flags. As rcxdude mentions this is something that you tend to care more about in statistical applications, and that's what R is for.
