Is there a rawtype() planned to act as previous versions of type() would?

I have been using this -rc for the last week. No issues to report.

And I'm really enjoying the __name in tostring() output!

Instead of introducing new function "rawtype()",
good old "type()" may return two values: raw type and "specialized" type:

local t = setmetatable({}, {__name = "MyType"})

print(type({}))  --> "table"
print(type(t))  --> "table", "MyType"

BTW, this way "math.type()" could be removed as it does not needed anymore:

print(type(42))  -->  "number", "integer"
print(type(3.14))  -->  "number", "float"
