Quadratic? In this kind of situation I'd understand linear, geometric 
and exponential. What's quadratic? Hmmm .... to guess ... well yeah, you 
must mean some combination -- an exponential vector + a geometric vector 
+ a linear vector, yes? My math skills aren't up to it, but they say 
there's a way of throwing a progression like those into an engine that 
returns the quadratic that best fits. Great fun if one could find it. 
Actually I did that once in Geogebra.

Please let me know when yourself and Bart have a final cut of slurp -- 
for a guy like me who thinks a copy should be a copy, not an edit, slurp 
seems an essential tool on principal. I can't understand how something 
so basic could not be built into the shell. Seems to me that at a first 
estimation one might want:

1) Full exact copy -- byte identical including blanks, newlines, 
trailing stuff and naughty chars. slurp.

2) Byte identical up to the last 'real' character -- yes, strip off any 
trailing garbage. This would be: > % copy=( "${(@f)original}" ) < , yes? 
Good enough 99% of the time.

3) As it is now -- no blanks. I myself have arrays in which blanks must 
be preserved ...

Hey ... How does all that work with associative arrays? It's one thing 
to remove a blank/empty element in a normal array, but in an A array ... 
even when there's no value, the keyword is still there, no? I'm thinking 
that A arrays must be auto-immune to removal of blank values, yes? But ...

main[currentE]=1 # Absolute index of the highlighted element (returned 
to calling fce on ENTER or mouse click). main[hilighted]=1 # RELATIVE 
index of the highlighted element relative to top of current page.

main[hilighted]= # Don't even think about doing this!

... I've noticed that if initializing an A array, there *must* be a 
value otherwise the pairs go out of whack. So, really, there never is an 
empty value and the issue is moot.
