For classes, we can eventually make it
so that all the methods and handlers (including the anonymous ones)
are declared at compile time in
a class declaration.
But what about views (i.e., instances rather than class declarations).
Maybe we say that they cannot
reference super() in their methods or handlers? That would be kind of
confusing. Especially as we
promote this style of programming where you first make methods on your
instance, and then
convert it to a class later. If you can't refer to super() in your
methods, you're somewhat restricted
for more sophisticated programming.
If a view has some methods or handlers declared, they get stuck into
the initial attributes list
as functions, like
<view bgcolor="blue" width="40" height="40"
x="59" y="59"
onclick="this.setAttribute('x', 10);
this.setAttribute('y', 10)"/>
{$delegates: ["onclick", "$m3", null], $m3: function
$hello$2Elzx_15_50_$m3 () {
this.setAttribute('x', 150);
this.setAttribute('y', 10)
},
One thought I had at one point was to convert every view that declares
methods or handlers into
a singleton class declaration, that seems like a pretty major step,
but maybe it's necessary!
Another thought;
I guess that for each user-class, the compiler could collect up all
the methods that are declared on all instances of that class,
and carefully map them to unique names and define them on the class,
but that seems a little
awkward. That seems even worse that making a singleton class for
instances that define methods.
