[ ArgumentList ] vs. @( ArgumentList )

[Walter Bright]

For User Defined Attributes.

In the north corner we have the current champeeeeon:

-------
[ ArgumentList ]

Pros:
    precedent with C#
    looks nice

Cons:
    not so greppable
    parsing ambiguity with [array literal].func();

------
In the south corner, there's the chaaaaallenger:

@( ArgumentList )

Pros:
    looks like existing @attribute syntax
    no parsing problems

Cons:
    not as nice looking
------

No hitting below the belt! Let the games begin!
