Attached.  It depends on the patch in 15611, so I'll commit both (maybe
altered) after I've gotten feedback.

[-- Attachment #2: Test various options and arguments to typeset --]
[-- Type: text/plain , Size: 4149 bytes --]

# There are certain usages of typeset and its synonyms that it is not
# possible to test here, because they must appear at the top level and
# everything that follows is processed by an "eval" within a function.
# This includes but may not be limited to printing all values (with no
# arguments) or all names (with argument `+').

# Equivalences:
#  declare	typeset
#  export	typeset -x (implies -g)
#  float	typeset -E
#  functions	typeset -f
#  integer	typeset -i
#  local	typeset +g (almost)
#  readonly	typeset -r

# Tested elsewhere:
#  Equivalence of autoload and typeset -fu 	A05execution
#  Associative array creation & assignment	D04parameter, D06subscript
#  Effects of GLOBAL_EXPORT			E01options
#  Function tracing (typeset -ft)		E02xtrace

# Not yet tested:
#  Justification (-L, -R, -Z)
#  Case conversion (-l, -u)
#  Hiding (-H)
#  Tagging (-t)

That's OK by me.  The `local foo[..]' stuff strikes me as way out enough
that as long as it works consistently the exact interface isn't so
important.
