The documentation for Class::Inspector says:
methods $class, @options
For a given class name, the "methods" static method will returns ALL the
methods available to that class. This includes all
methods available from every class up the class' @ISA tree.

So you need to assign the return of Class::Inspector->methods to a scalar
and later defererence the reference.
You could make these changes:
my $methods = Class::Inspector->methods('IO::File', 'full', 'public');
print @$methods;
# consider print join $/, @$methods;
and you'll get a list of methods.
