The type of a Sieve argument may not be known at compile time. Use this with caution during compile callbacks in extensions.

If you want to find out the type of argument returned by `sieve_parse_args` and its "%", "@" or "*" placeholders, use [sieve_get_type_of_arg](/momentum/3/3-api/apis-sieve-get-type-of-arg) instead.
