How about Adding/Overloading Some Operators for Signal to Make Signal Operations More Readable

[Lazy-Rabbit-2001]

(I don't know if hers is a good place to talk about it, nor do i make it clear that if someone has mentioned this idea before)
As is known to all, signals are now belong to a native class Signal, which allows us to directly connect them to methods (Callables).
However, most of times we are prefer to use a operator to connect signal, just like how it is done in C#.
My thought is to add some operators like "==>" to be meant as "connect()[without flags]", "=/=" as "disconnect()" and "=?=" as "is_connected()".
For example

signal my_signal
...
my_signal.connect(my_func)

# Replaced by operators
# Equals "my_signal.connect(my_func)"
my_signal += my_func 
#or
my_signal => my_func # Returns an int

# Disconnection
# Equals "my_signal.disconnect(my_func)"
my_signal =/=> my_func 
#or
my_signal -= my_func # Returns nothing

# Check
# Equals "my_signal.is_connected(my_func)"
print(my_signal =?=> my_func) 
#or
my_signal == my_func # Returns True/False, here it's obviously 'false'

If we need to pass in a flag, we can add a method bind_flags() for a Signal

# Equals "my_signal.connect(my_func, ...)"
my_signal.bind_flags(...) => my_func

When it comes to signal emission, we can use an operator ++ to mean "emit", and add a method bind_params() to make it emitted with parameters

# Equals "my_signal.emit(1, 2, 3)"
my_signal.bind_params(1, 2, 3) ++

Developers are still allowed to use methods to connect, disconnect, emit and check signals

How do you like this idea? Please share yours in this post :)

We prefer keywords and methods rather than symbolic operators. There are a few exceptions ($Node, %UniqueNode, &"StringName", etc.), but they are due to frequency of use and shortening the code (no quotes and parentheses). In this case, this does not reduce the time to write the code (due to autocompletion), but it significantly worsens the readability.

Perhaps the += and -= shortcuts for connect() and disconnect() look ok to those coming from C#, but the rest of the operators look confusing to me and won't be useful for other data types.

[Lazy-Rabbit-2001]

Maybe += and -= could be friendly for those developing with C#. As for is_connected(), it's very difficult to think about an operator.
Anyway thanks for your comment :)
