Recalling the previous discussion of throwing exception being costly, I
thought the idiom of "pay as you go" is worth incorporating into the
standard library.
In brief:
throw exception("CPU temperature is below", 2.5, "K");
vs
throw new Exception(text("CPU temperature is below", 2.5, "K"));
or:
enforce(false, text("CPU temperature is below", 2.5, "K"));
The benefit that the latter will only construct string if printing is
indeed requested.
Proof of concept:

The problem with it is that for some reason writeln of exception won't
compile while thrown exception is printed just fine by the trace handler.
Thoughts?
