you're passing types to next, and it points out correctly: no method
matching next(::*Type*{Number}, ::*Type*{Any})
method_exist on the other hands takes types as its arguments so your query
should look like this:
*method_exists( next, Tuple{DataType, DataType } )* or *method_exists(
next, Tuple{ Type{Number}, Type{Any} } )*
which correctly returns false.
