mawk wish list

mawk_wish_list
mawk 1.3.4 from Thomas Dickey http://invisible-island.net/mawk/
his mawk is even faster than mawk 1.3.3
on some things like array references it is 3X ~ 10X faster than awk or gawk

see file http://invisible-island.net/mawk/CHANGES for list of changes since 1.3.3
eg he has added POSIX character classes;
WHINY_USERS sorted-array feature;
nextfile; "/dev/stdin" name for stdin
My wish list for mawk:

1)	a mawk64.exe for windows 7 - 64 bit.
2)	the -W source  switch as in gawk
3)	system() is broke in mawk.exe / windows 7 - 64 bit (although pipes work fine ??)
	eg system("anything")  throws up a windows dialog that mawk is not responding ....
4)	length(array)  and 2**3 for 2^3 (use ** or **= in place of ^ for exponention)
5)	spilt(s, A, //)  same as spilt(s, A, "")

see:
http://brenocon.com/blog/2009/09/dont-mawk-awk-the-fastest-and-most-elegant-big-data-munging-language/
for interesting discussion of mawk performance.

from irc://freenode.net/#awk

mawk.exe 1.3.4
%mawk% -v n=2e6 "BEGIN { while(n--) A[rand()]=rand(); for(i in A) j++; print j;}"
took 9.2 seconds whereas gawk.exe 4.0.1 took 26.2 seconds
