good luck, dude!
Comment 4 Graydon Hoare 2005-10-20 22:15:59 UTC 
version in CVS now handles 

global log_hist(foo,NBUCKETS) 

and 

global linear_hist(foo,LO,HI,STEP)

as "quasi scalar" variables and as statistic-valued maps. can't be copied, can't
be assigned to or from. operator <<< inserts pe_long values into stats,
expressions of type <<< are pe_long, expression value is the inserted value. not
lockless as advertized; they're currently just as SMP-expensive as any other
sort of variable. 

only rudimentary (build-stage) testing, no print or inspection operators, no
changes to docs yet.
Comment 5 Frank Ch. Eigler 2005-11-30 16:39:00 UTC 
Is it an accident that the translation of the "<<<" operator currently causes an
exclusive (write) lock to be taken on the stats array for the operation?
Comment 6 Graydon Hoare 2005-12-10 05:58:34 UTC 
Final bit of functionality for this (histograms in pseudo-array contexts) should
finally now be committed. Let me know if you find further missing support.
