With the +use of metamethods, several of these functions are provided as infix or prefix +operators. On the one hand, the result is usually much more verbose than the +typical encoding of patterns using the so called regular expressions (which +typically are not regular expressions in the formal sense). On the other hand, +first-class patterns allow much better documentation (as it is easy to comment +the code, to break complex definitions in smaller parts, etc.) and are +extensible, as we can define new functions to create and compose patterns. |
