The any type
The any type is a type used internally by Bro to bypass strong
typing. For example, the fmt function takes arguments
of type any, because its arguments can be of different types,
and of variable length. However, the any type is not supported
for use by the user; while Bro lets you declare variables of type any,
it does not allow assignment to them.
This may change in the future. Note, though, that you can achieve
some of the same effect using record values with &optional
fields.
