-// ^ marks the "key" token; this is used only after parsing
-// / separated-by; all preceding elements are separated by the following element
-// +/ one-or-more-with-separator; for example, "a"+/"," matches "a,a,a"
-// */ zero-or-more-with-separator
-// & intersection; a&b matches a string only if a matches it and b matches it
-// &~ negated intersection; a&~b matches a string only if a matches it and b DOES NOT match it
