Given the wide disparity of functionality, I'm wondering if there are concrete
purposes for these new matchers?

This code does not look legal to me because of the `X:`. (Same for the Example

I think it makes more sense to extend hasAnySubstatement() to work off
stmtExpr() in addition to compoundStmt(). Same may be true for
statementCountIs(), if you need it.
