Okay.  Furthermore I've changed the index variable from an x to an i
because it's an index variable instead of an unknown, which addresses
the fact that none of the first four examples care at all about the
value of $x, and it should please any old fortran programmers who might
stumble into the passage.  IMO splice
doesn't even need to fetch its data arguments and should manipulate
aliases, just to cause more problems.  Maybe in an ideal world,
C<splice> (and the four instructions that one mistakenly (?) imagines
are sugar for it) would work with COW aliases instead of values.  And
we could use indentation to indicate blocking, instead of all these
damn curly brackets. (The sentence previous to this one is a joke.)

Do we have copy-on-write assignment yet?  I know it's been discussed
here before. What's its current status?  I guess COW_ALIAS
would have to be yet another tie primitive then, and a TIESCALAR package
that didn't provide it would default to FETCHing.


David Nicol, independent consultant and contractor
have a nice day, really.
