Suggestion for two-way binding shortcut in angular2

gistfile1.html

<!-- Current -->
<input bind-style.color="mycolor"
       on-change="mycolor = $event.target.value"
       on-custom-event="mycolor = $event.target.value">
<input [style.color]="mycolor"
       (change)="mycolor = $event.target.value"
       (custom-event)="mycolor = $event.target.value">

<!-- Maybe consider -->
<input bind-style.color:change:custom-event="mycolor">
<input [style.color](change)(custom-event)="mycolor">

<!--
Short-curcuit databinding by listing event names between the bound property name
and the bound expression. The expression must have property access syntax
(not a function call, not a ternary, etc.). On each of the listed events,
the element property value is fed back to the component.

In this example, on `change` and `custom-event`, the current `<input>.style.color`
is assigned to `<component>.mycolor`.
