Yes ... as of the current patches, namespaces are not significant
except that parameters in namespaces don't show up in "set" /
"typeset" output (unless asked for).  It's an unresolved question
whether to implement the ksh "namespace" keyword and its effects.

This thread is about whether (and potentially which) identifiers we
want to declare as reserved for the shell's own purposes.  To that end

I'm presently thinking about a namespace "interact" to group variables
that apply only (or mostly) to interactive shells.  Then for the
original "Colemak" question we'd have something like:

typeset -gA .interact.keyboards=(
 [QWERTY]=$'\n\n\n\n\n\n\n\n\n\n\n\n\n\n'\
$'\t1234567890-=\t'\

$'\tasdfghjkl;\'\n\t'\
$'\tzxcvbnm,./\t\t\t'\

.interact.layout=${.interact.keyboards[Colemak]}

and change utils.c:spdist() to check getsparam(".interact.layout")
before examining the DVORAK option (for backward compatibility).
