[Q] Should with support the filter syntax `|filter(arg1, arg2)`

[vicb]

See the discussion in #758. I'm creating the issue as the PR should be closed soon.

TL;DR:

1. The current syntax is |filter:arg1:arg2 and comes from Django & Smarty,
2. The proposed syntax |filter(arg1, arg2) comes from Jinja & Twig

The proposed syntax should allow for named arguments as well.

If we go for the second syntax and support named arguments, the current syntax should probably be dropped.

Thoughts ?

Two 👍 for option 2. IMHO, AngularDart should match Dart syntax and semantics to every extent possible. (And the influence is two way: e.g., as you already know, that is why I asked for function pipes to be added to Dart.)

👍 option 2 (for me this is call/parameter list syntax for any C like language (I have no idea what Django/Smarty/Jinja/Twig are)

This still in the works?

After having discussed with @mhevery, the status is that the current syntax is fine unless an other one would have obvious benefits

For ref, polymer does support formatter(arg), see https://github.com/dart-lang/bleeding_edge/tree/master/dart/pkg/polymer_expressions#two-way-bindings

Great! Again, I vote for this in Angular too.

I vote for this too.
I still have a hard time to remember the current syntax because nothing similar exists anywhere else in Dart. It's just unintuitive. Every time I needed this I had to look the syntax up.
Maybe I should learn Django and Smarty ...
