Here is an interesting discussion from the julia language where string concatenation is indeed the * operator: https://github.com/JuliaLang/julia/issues/1771 https://github.com/JuliaLang/julia/issues/1771 In particular: https://github.com/JuliaLang/julia/issues/1771#issuecomment-23035083 https://github.com/JuliaLang/julia/issues/1771#issuecomment-... Undoubtedly, it is a big surprise for new users (without exposure to free monoids :-)), that * is string concatenation. By the way, in python juxtaposition ("abc" "def") is also valid.
