Perhaps if StringInterpolation.interpolate instead of taking a
contextScanner and an escaper published events like ('Literal, "foo")
or ('Substitution bar) to an interpolationEventSink then the current
contextScanner&escaper could be built on top of it, or an
implementation could route those events to an AST builder instead.

I'd expect to have "openedTemplate(...blah...)" as an abbreviation for "open(Template(...blah...))", although maybe a name shorter than "openedTemplate" should be selected.You didn't miss anything. This is an implementation detail leaking
out through the API.
The `Template` part converts the "Hello $name_of_planet!" to "new
StringInterpolation(['Hello ', name_of_planet, '!'])" and the `open`
part is really `eval` in disguise which parses the string and invokes
the constructor. Thus, two function calls are needed for this macro

Now that ANTLR 3 has a retargetable backend, this might be a good
perl, Python & Ruby are all implemented as examples to draw upon. See
