Can OP_NOTIF begin an if/else block? That is, is the following code valid:
<true / false stack item>
OP_NOTIF
<some script to be executed>
OP_ENDIF
Or does an if/else block need to always begin with an OP_IF?
I assume I am correct that you can begin with OP_NOTIF, and that the above script code is valid, but I wanted to double check.
