Cancellation of FuncSug code
All block
{...}can be aborted by labelling the block (with@label) and issue.break blockLabel.Internally, when labelled, the block is then surrounded by a "cancellableExec" instruction.
At each "micro-step", the "cancellableExec" instructions are verified and the cancellation is propagated to all the descendants.
Cancellation of JavaScript code
For cancellation of incorporated JavaScript code, the
extinstruction has an optional parameter to specify what to do to "rewind" this JavaScript code.
