Well, frankly I really don't like the idea of using OP_2 just to avoid chan= ging some unit tests. We're doing something that many people will use for years = to come, that's unnecessarily obscure just because we don't want to spend a bi= t of some modifying some tests to pass. OP_TRUE is the obvious way to do this, and it results with a 1 on the stack, which plays better with other standardness rules. OP_2 means we *also* may = need to special case having a 2 on the stack in certain implementations of other standardness rules. --=20 https://petertodd.org 'peter'[:-1]@petertodd.org --4pHyXnTH3anttqOW Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEE0RcYcKRzsEwFZ3N5Lly11TVRLzcFAmPcG4cACgkQLly11TVR Lzf8yw//SaKXXFrM6Yf6esphFghNZ0SY5dFFSa6E8iF5ZGT+5B8BC1UrPCcDjDQI tuymAlq78OgTrzPa3QXGsueq7rvUaBs+a/5JgONF7Q0dXh4APpCafQ+Fe5HJ4h7V DXfa2WT05ioAABEoQ9YPduwit0aC93UHI59unq4EkLxjzqVTc5YbCpYzNFsmT4Eg /ekROQJpbIRLYxl+DsDvv7YiGbaOlWoV3GBJVBN0GpIjclGEBSv47gA7QusHrfBk ng3Kdxcek9MFJYHPl7fF4W4NyZSJKadjuUIA041YT0bzlzgkO/KApSdFPkHhn0dj G4U4yvDbR1zBglEvpo6yuRzZP4/pZJM8pPeeBwIGPIbWp87TMznbylgYNiTShBeM yLVNCqUYBIi7NIABYCAr7G1QaEhVmufdgCNk/4oDXYH9oiR14z7w9Fm1r26HMJEw bEo3i1+SeRCHa9GJdAuzPkoQ+uqw/FJkYO9R4+lHfzzq8sOPNzDwtyaG0VVHD3zp WLpQLaz/bdl2vD/X00DzlpP737ywKWMMnzOkz4uAxPmeNi22OjbjDz4G9akelgsg 2Iq7GLb5ZVxan7i9UVLpzZwXTatlmLJW5lDmD+yW7mL0QdQw5/KIv4Hlhi0Hn2bw ev6nB23GEoVU7nrTJ6J0ItnYzfzRVzgGB4mgeIoYa5mcvps3lQg= =Lt2o -----END PGP SIGNATURE----- --4pHyXnTH3anttqOW--
