The typeof function currently uses three arguments that appear to be quite redundant (and are not documented other than a single example). The documentation is outdated too, mentioning that only ClassOrInterfaceType is supported

What I gather is

• First arg is always @Image -> this could be inferred from the context node, just like the metric function is called with simply metric('NCSS').
• Second arg is FQCN of the type we want to match
• Third arg is the simple name of the type -> redundant, could be inferred from the FQCN

I think we could create a new function (for compatibility), e.g. typeIs (this name seems clearer anyway since it returns a boolean), that you could call like:

//ClassOrInterfaceType[typeIs('java.lang.StringBuilder')]
