Can we extend parseTemplate in typescript plugin? since it seems to me that TemplateInterpolation is a TS-only concept.

Isn't it the same concept as for js? i.e. a${x}b is valid both in TS and in JS.
Maybe if I call it parseTemplateSubstitution, which is the language used in the spec?

This is a type analysis error, it can't be caught at parse time.
