ParserError when parsing for..in using contains

[rhartig-ct]

yaramod fails to parse the following rule

rule test
{
    meta:
        description = "Test yaramod"
    condition:
        for any s in ("foo", "bar") : ( "foobar" contains s )
}

With error yaramod.ParserError: Error at test.yara:6.50-57: operator 'contains' expects string on the right-hand side of the expression

Error occurs starting in version 3.21.0, before that it gives an error that integer set expects integer type.

I'm guessing that this has to do with Yara 4.0 allowing for..in to iterate over things other than numbers. While yaramod does parse the for..in portion correctly, but when parsing the condition contains thinks s is an int, when it is really a string.
