[Bro-Dev] Use of 'any' type

It would be most convenient if the 'any' type could defer type checking
until runtime at the script level.
For instance, if both A & B are defined as type 'any', a compile time error
"illegal comparison (A < B)"
occurs upon encountering a bro statement
if (A < B) do_something();
even if the actual values stored in A & B at runtime are integral types for
which comparison makes sense.
If the decision could be made at runtime (which could then potentially
throw an error), a number of useful generic functions could be created at
the script level, rather than creating yet-another-bif. A useful
yet-another-bif would be 'typeof' to allow varying code paths based on the
type of value actually stored in 'any'.
