PM_TAGGED and PM_TAGGED_LOCAL being set simultaneously (functions -T -t f)

[Daniel Shahaf <d.s@xxxxxxxxxxxxxxxxxx>]

As y'all recall, «functions -T» and «-t» set the XTRACE option for calls
to the named function.

With that in mind, in the following code:

[[[
f() g
g() :
functions -T f
functions -t f
f
]]]

Should XTRACE be on or off when g is run?  Or should an error be raised
before g is called?

And if -t were set first and -T second?

Cheers,

Daniel
