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='()'

[14]="/usr/sbin" [15]="/home/law/bin/lib" [16]="/etc/local/func_lib"

# 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... ;-)
