We can improve(1) the write side cpu time by -7.0% and the elapsed time
by -9.3% by not using rand.inc's (VRand(rng_)) macro, but rather:
#local arr_[i_] = array mixed  \
Further, it appears the macro caching of VRand() is somehow tangled in
the increased system time v3.8 beta to p380 branch/povr - I still don't
see how. It still might be that if that cause could be run down, one
could use VRand() without as much penalty.
(1) - To speed compiles I dropped the link time optimization. The
improvement where configuring with --enable-lto will be somewhat different.
A big chunk of the time is in the scanner.cpp code qualify bits and
pieces of potential tokens. As to how to make that all 'significantly'
faster within the current framework - no luck thus far. We'll see.
