I’d like to use ‘+’ operator for string concatenation. but it is ‘*’ in Julia. If possible I’d like to define ‘+’ as alias of ‘*’ if opland are strings. because some insufficient definition cause some side effect. Thanks in advance!!

See also the Julia FAQ: Why does Julia use * for string concatenation? Why not + or something else? In general, when you learn a new language, you should try to learn the idiomatic “spelling” of things in that language. Trying to write code in Julia that superficially resembles some other language…

Is it possible to define '+' operator for string as '*' do for them?

Take also a look at this thread and the tiny Julia package PlusPlus.jl with just three lines of code.
