Currently it is not possible to leave the alt-statement from within the altstep. A construct which will allow this is more than a break-statement, because a break is an unconditional jump to a known place (i.e., a goto-label-construct).<br />
<br />
The technical study of a break-like construct for altsteps should consider that altsteps<br />
- are introduced/used as functions and not as macros,<br />
- have scope,<br />
- may have in, inout and out parameters,<br />
- can activated as defaults.<br />
