That actually doesn't make sense to me. 2::second has no reference point to
when it started or when it ends. It's just 2 seconds of duration. So, for
2::second $ time => time later;
seems so implicit that it's ambiguous. I would, however, agree that there
ought to be a (dare I say) keyword for the time at which the VM started so
that you could basically do the same thing that you did in the first line.
vmstart + 2::second => time afterVmStarted;
Of course, you could just approximate this functionality by having this line
run the moment the vm starts:
now => time vmstart;
Then, you'd be able to the do everything relative to that time. At least,
that's how I would solve it.
