A simple looper.
@loop call
@loop n call
@loop bool_expr call
@loop 1.0 callRepeat call indefinitely until interrupt or n times and discard the output.
If an expression is given as a first argument it must return a Bool and
repeats will occur until false. If a float is given the loop will run for that
many seconds.
julia> @loop println("Hello, World!")
Hello, World!
Hello, World!^C

julia> @loop 2 println("Hello, World!")
Hello, World!
Hello, World!
julia> @loop rand() > 0.5 println("Hello, World!")
Hello, World!
