Consider supporting call for pseudo commands

[jquesada2016]

Assume there exists a <dialog id="modal" /> on the page.

If I try:

<button _="on click show() the #modal">
Show Modal
</button>

Then this doesn't work, because show is a command, and therefore the () are syntax errors.

I therefore need to instead do:

<button _="on click call show() of #modal">
Show Modal
</button>

In order for it do be correctly interpreted. This is fine, to disambiguate. But what about supporting:

<button _="on click call show() on the #modal">
Show Modal
</button>
