the documentation for HTML::Mason::Interp->set_globals <http://
masonhq.com/docs/manual/Interp.html#item_set_global> shows the usage:
set_global ($varname, [values...])
which suggests that the values are optional.
however, the code disagrees:
sub set_global
{
my ($self, $decl, @values) = @_;
param_error "Interp->set_global: expects a variable name and one
or more values"
unless @values;
[..snip..]
this makes it difficult to assign an empty list to a global array:
$interp->set_global( '@foo' => @foo );
i have had to resort to:
undef @HTML::Mason::Commands::foo;
$interp->set_global( '@foo' => @foo) if @foo;
undef %HTML::Mason::Commands::foo;
$interp->set_global( '%bar' => %bar) if keys %bar;
which works but is not ideal. i could probably skip the set_global
altogether here, and just
@HTML::Mason::Commands::foo = @foo;
but i would prefer to stick to the provided interface as much as
possible.
either way, either the documentation or the code needs a patch!
