Re: Call-by-value (eager) vs. Call-by-name (lazy)



(to John) What is (was) "Jensen's device"?

Vaughn says
	"with call-by-value the programmer gets fine control over
	the timing of evaluation, by judicious choice of quotes".
Most of the programming I find myself doing is the most awful kind
with shell-scripts and the like (for text-processing odd jobs).
In these circumstances choice of quotes is far from judicious,
it seems totally arbitrary!
