Feature #10406

Method starting with a capital is not detected when parentheses and receiver are omitted

Description
A method whose name starts with a capital is not detected when parentheses and receiver are omitted.
def Foo; puts "foo" end
Foo # => uninitialized constant Foo
If I disambiguate it as a method, then the method is detected:
Foo() # => foo
This kind of consideration if unnecessary if the method name does not start with a capital.
def foo; puts "foo" end
foo # => foo
So I expect method Foo
to be detected without explicit receiver and arguments (unless there is a constant with the same name).
def Foo; puts "foo" end
I first thought this as a bug. If it is not a bug, then I would like to ask this as a feature request.

It's a ruby's naming rule.
I believe this is intentional. Otherwise, we would become unable to refer Array, Integer, Float, String, and Hash classes because of Kernel#Array and so on ;-)

Just like local variables have precedence over method look up, I expect that constants have precedence over method look up, so I don't think that would be a problem.

Unlike local variables, constants are not resolved statically. That's the reason behind this behavior.
If you have further demand, reopen the issue.
