Documentation on variables unclear

[patrickbkr]

The documentation on variables states The <$...> syntax can be used to refer to a variable. At that point in the documentation subroutines are not introduced yet. So it's easy to assume this refers to Raku variables accessible in the context of the render-template() call.

From my experience this is not how it works. Skimming through the webapp tests, there are no tests for this either. The only tests there are test accessing template subroutine parameters.

If I'm right with this, then the documentation should be more clear on what kind of variables can actually be accessed.
