scope of identifier names in lowered syntax forms #25947
Closed
Description
Is this behavior intended?
julia> f(c) = 1:5 ;
julia> f(0)
1:5
julia> g(colon) = 1:5 ;
julia> g(0)
ERROR: MethodError: objects of type Int64 are not callable

If so, is it documented anywhere what variable/function names could change behavior, or could the names used by changed to be more "internal-looking" (e.g. __colon__ instead)?
I can see how the behavior is a potentially useful feature:
julia> function f()
colon = function (args...) ; println("args: ", join([args...], ' ')) ; Base.colon(args...) ; end
1:5
end
f (generic function with 1 method)
julia> f()
args: 1 5
1:5
