Control how a pattern is matched to an expression.
substitution: if present, assumes these values for the named wildcards, and ensure that subsequent occurence of the same wildcard have the same value.
recursive: if true, match recursively, otherwise match only the top level.
numericTolerance: if present, the tolerance for numeric comparison.
exact: if true, only match expressions that are structurally identical. If false, match expressions that are structurally identical or equivalent. For example, when false, ["Add", '_a', 2] matches 2, with a value of _a of 0. If true, the expression does not match.
