Why is this invalid syntax?

[Marshall Lucas]

OBJ->method()

Why must I call the method as:

OBJ->method

without the ()?  I'm allowed to use them on a function:

x = OBJ->function()

Just curious about this one as it drives me insane because I have a natural tendency toward always supplying the () for a method call.  I'm slowly learning not to do it.

Hi Marshall,

 

Brackets would imply that it is a function that returns a value.

But by that same line of thought:

OBJ->method(arg1)

would imply that it is a function but of course it doesn't, being an rvalue makes it a function, not the ().  

lvalue = OBJ->rvalue()

however:

OBJ->method() 

is simply a call to a method without supplying any arguments and not being able to use them seems a bit inconsistent when you can use them on a get (function) method.  

That's just my $0.0002 worth (not even 2 cents).

Hi Marshall,

 

To save further discussion on this topic, we have made a change to allow use of empty brackets on a method subroutine reference. This will be in release 3.0-2 (no date set yet).

Wow!  Cool, didn't really expect it this time.  But thank you so much.  I feel quite priviledged now!

Martin and company are really quite amazing.  I was just reading another thread about what it takes TL to make a change to D3 and it is a vastly different attitude.  Thank you Martin.
