Nice. I see they’re using the latest unicode. Does anyone know if it will be possible (an supported by Julia) to express negative one “-1” as a superscript w/ unicode? X^{-1} is a lot leaner than inv(X) or X^-1

You can actually do this with no language changes if you’re willing to write (A)⁻¹ rather than A⁻¹. Here’s an example at the REPL: julia> begin struct Inverter end const ⁻¹ = Inverter() Base.:(*)(A, ::Inverter) = inv(A) end julia> A = rand(3,3) 3×3 Array{Flo…

Solving a linear system by Gaussian elimination is a constant factor 4 faster than finding the inverse [Trefethen, Numerical Linear Algebra].
