Nah, no need to post the original, I think. I believe the problem is
that you're
using the null-method syntax to call your sub ref. The "$subref->
(@args)" syntax
is standard Perl but gets overloaded by NiceSlice -- constructs of
that form get
changed to "$subref->nslice(@args)" by a source filter.
If you change your sub call to "&{$s}($x)" I believe it will work
better.

I suppose I could post the original code.

Subject: Re: [Perldl] Can't call method "nslice" on unblessed
reference
Hi Steve
my $s = sub { 1; };
my $x = sum($a->slice("0:0,1"));
$s->($x);
It isn't clear to me what you intend to do here - $s is reference to a
subroutine so -> cannot act on this (which is why you get the error).
What is the intention with the code?
Cheers,
Jarle.
