Class KeyExpr

Performs string concatenation and returns the result as a KeyExpr if possible.

Returns true if this includes other, i.e. the set defined by this contains every key belonging to the set defined by other.

Returns true if the keyexprs intersect, i.e. there exists at least one key which is contained in both of the sets defined by self and other.

Joins both sides, inserting a / in between them. This should be your preferred method when concatenating path segments.

Returns the canon form of a key_expr
