[2016-06-24 01:22:55] <petertodd> after evaluation of any opcode?
[2016-06-24 01:24:17] <jl2012> after evaluation of the script. But EXPANDs will terminate the evaluation immediately
[2016-06-24 01:24:33] <jl2012> a bit similar to Satoshi's original OP_RETURN
[2016-06-24 01:24:51] <petertodd> ah, right
[2016-06-24 01:25:08] <petertodd> hmm... seems like a potential footgun
[2016-06-24 01:26:22] <jl2012> yes, that could be risky. I made this proposal before we expand the definition of witness program from 32 to 40 bytes
[2016-06-24 01:26:36] <jl2012> This may not be necessary now
