        Yeah, but they seem to get propagated anyway, I must save it somewhere 
like
I do _FPATH... i.e. each include adds teh included script into the INC array so
I don't
try to re-include it.

Note after I change the PATH, the _FPATH array is automatically updated as well

Ishtar:law> include stdalias.shh
declare -Ax _INC='()'
declare -ax _FPATH='([0]="." [1]="/sbin" [2]="/usr/local/sbin"
[3]="/home/law/bin" [4]="/usr/local/bin" [5]="/usr/bin" [6]="/bin"
[7]="/usr/bin/X11" [8]="/usr/X11R6/bin" [9]="/usr/games" [10]="/opt/kde3/bin"
[11]="/usr/lib/mit/bin" [12]="/usr/lib/mit/sbin" [13]="/opt/dell/srvadmin/bin"
[14]="/usr/sbin" [15]="/home/law/bin/lib" [16]="/etc/local/func_lib"
[17]="/home/law/lib")'

Ishtar:law> PATH=~/bin/lib:$PATH
Ishtar:law> include stdlib.shh
declare -Ax _INC='([stdalias.shh]="/home/law/bin/lib/stdalias.shh" )'
declare -ax _FPATH='([0]="/home/law/bin/lib" [1]="." [2]="/sbin"
[3]="/usr/local/sbin" [4]="/home/law/bin" [5]="/usr/local/bin" [6]="/usr/bin"

# I execute a 2nd bash, but notice -- INC and FPATH were both propagated to the
child and both
#  are of the correct type

(so guess that wasn't an explanation)

Unfortunately, if I try to include needroot, it tries to re-exec the original
program, which
doesn't work so well in an interactive shell... ;-)
