Subject: Add $find(<sequence>, <value>), $find_index(<sequence>, <value>)
 functions

The $find() function returns true if the sequence contains the specified
value. The $find_index() function returns the index of the first element
in the sequence that is equal to the specified value or $size(<sequence>)
if none is found. For string sequences, it's possible to request case-
insensitive comparison with a flag.
