Conflicts with Underscore.JS

[tauren]

Inside of the function tiCalls(), the value of _ is set to the content. This makes it more difficult to use the Underscore.JS library ( http://documentcloud.github.com/underscore/ ) within a template.

I'd like to propose that __ (double underscore) be used inside of jquery.tmpl.js instead of _ (single underscore) to avoid this collision.

If this change is likely to break existing templates, then perhaps there could be a noconflict option that would avoid using a single underscore and leave it as it was inside the template processing context.

For instance, with the following data:
var objects = {a:1, b:2, c:3};

This template won't work:
There are ${_.size(objects)} objects.

This can be worked around by defining a new global for underscore:
var underscore = _;

Then in the template:
There are ${underscore.size(objects)} objects.

I'd vote for reserving _ for underscore.js. This lib is of wide use, good would be to just respect this.

Afaik the _ variable is only internally used and not a part of the documented public API (see http://api.jquery.com/category/plugins/templates/ ). So it should be safe to rename it.

Exactly. Please consider renaming.

This is already being tracked as https://github.com/jquery/jquery-tmpl/issues/#issue/10. It will be renamed. See linked issue...
