# 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.

# Equivalences:
#  declare	typeset
#  export	typeset -x		and typeset -x implies -g
#  float	typeset -E
#  functions	typeset -f
#  integer	typeset -i
#  local	typeset +g -m		approximately
#  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)
#  Assorted illegal flag combinations
