That definitely seems more useful than "any".

It would be a prettier and more consistent syntax for bundles that fulfill a
promise for the name of something passed. For example, a files promise might
look like:
files:
"/my/file" perms => mog( "644", "root", "root" );
It's fulfilling some desired state for /my/file.
Now let's say I want a bundle to fulfill some desired state for /my/file.
Today it seems that we have to do this:
methods:
"not-used" usebundle => my_bundle("/my/file", "some-other-parameter");
But what I'd rather do is:
methods:
"/my/file" usebundle => my_bundle("some-other-parameter");
I realize this may not be useful for desirable for all kinds of bundle calls.
But I can see it being useful in many situations. That way the language could
be used consistently for methods: promises and other kinds of promises.

A new variable would be fine.
The reason I thought of $(this.promiser) is because it seems like
$(this.promiser) references that same left-hand-side value for files:
iterations and searches.
You're calling that left-hand-side value a comment in methods: calls, but it's
definitely not a comment value for other types of promises. So I'm just
suggesting that it be made consistent, and it seems like all we need is a way
for the called bundle to access that left-hand-side value.

I occasionally work with people there, so we definitely may have crossed paths
in the past. Nice to hear from you again if so. :)
