I would totally want that! Specifically, `a+b = a + b` where `a + b` is an expensive operation. Julia allows stuff like that to some extent, e.g. https://github

I would totally want that! Specifically, `a+b = a + b` where `a + b` is an expensive operation. Julia allows stuff like that to some extent, e.g. https://github.com/JuliaQuantumControl/Krotov.jl/blob/3132f0812de19c87e5083af2c5cad9f884eaf394/examples/perfect_entanglers.jl#L89-L99 https://github.com/JuliaQuantumControl/Krotov.jl/blob/3132f0..., but unfortunately not with `+`
- kaba0 4y agoWhy not just give it some temporary name, like ‘t’, supposedly it is only used in a very tight scope. Haskell and similar languages often do these things with `let in ..` or `.. with t=a+b`.
- goerz 4y agoBecause `a+b` is a much better variable name than `t`? Why `t`? If anything, `a_plus_b` or `apb`
- kaba0 4y agoNot really better at all, but I feel this is a bit contrived example. If it really is just numeric addition that just let the compiler do its job, otherwise I’m sure there are better names for whatever you actually try to do. And, random helper variables are a thing even in math, you don’t name the thing the way you calculate that thing because then you don’t spare any character.
