Does it make sense to use + for list concatenation?

@socks I feel like the behaviour we would intuitively expect would be that {1,2,3}+{4,5,6} yields {5,7,9}
-F

@Felthry Ah, so the same operation but lifted! I guess that would make sense

@socks we're also very used to matlab though, it might be less intuitive for others

matlab is heavily matrix-oriented so operations generally behave as they would on matrices; that's just how matrix addition and subtraction work. * is matrix multiplication, and / is actually a complicated operator that computes the inverse of the matrix on the right and left-multiplies it by the matrix on the left (there's also \ for inverting the matrix on the left instead)
-F

@socks it does have the useful feature that putting a . before any operator performs that operation separately on every element of two equal-sized matrices. So .+ and .- are the same as + and - but A .* B multiplies A₁₁ by B₁₁ and A₁₂ by B₁₂ etc, which is a really handy thing to have a dedicated syntax for instead of some function name you have to remember
-F

@Felthry Yeah, so that's just map then

@socks maybe that's a really common thing i dunno

matlab is the only high-level language we usually work in
-F

@Felthry Well, Matlab is extremely domain-specific. When I talk about programming concepts I talk about stuff that can apply to many programming languages for many different purposes
