Typical "list context" vs. "scalar context" thing.
When you assign a list to a scalar, Perl evaluates the list in scalar
context, which converts the list to a scalar whose value is the number
of elements in the list ('1', in your case).
Either of:
my ($hostref) = @_; # assigning to a list
or
my $hostref = shift; # assigning from a scalar
should do nicely.
