tagged doesn't support regular expression, it appears to support an
array but it's requiring all tags in the array to exist. You should be
able to do this instead:
if tagged('test_env') or tagged('stg_env')

Try using the fully qualified namespace to access the variable
(something like path to staging directory), so
class a::param {
$pkglist = ...
}
define ... {
notice($a::param::pkglist)
}
or pass it as a parameter if it changes per resource declaration.

Yes, the only thing that confuses new user, is you can't use if & case
statements in a resource declaration.
type { 'title':
# can't have if or case statement within resource.
# only selector
attribute => $var ? {
...
}
}
if ... {
# declare resources.
type { "title":
...
}
}
