Why not .* and kron?

[dlfivefifty]

I’m confused on the roll of this package: why not just use .* (instead of hardamard ) and kron (instead of tensor)?

[timholy]

This package is to unicode operators ⊙ and ⊗ what IntervalSets.jl was intended for ... We'll hope it's easier.

JuliaGraphics/ColorVectorSpace.jl#126

OK to close?

[dlfivefifty]

I get that, the questions was more about the functions themselves. Eg why not

hardamard!(dest, A, B) = broadcast!(*, dest, A, B)

(I guess with bounds checking to prohibit vector special cases)

[timholy]

Yep. Also more compiler-friendly. (broadcast is expensive.) But this seems a question about implementation rather than purpose, and of course we'd be happy to have improved implementations.

[dlfivefifty]

For custom arrays (like BandedMatrix) broadcast will likely be faster than using indexing so a more sensible default

[timholy]

Fair enough. PR would be fine.
