in reply to query for methods?

Is there way to determine method/function names for loaded module?
Yes there is and it's the can method which is attached to every object. Here's a short example of how to use it 
package Foo;

sub new { bless {}, shift }
sub foo { print "i'm a method of Foo\n" }

package main;

my $o = Foo->new();
print "foo exists\n" if $o->can('foo');
print "bar does not exist\n" unless $o->can('bar');

__output__

foo exists
bar does not exist

    This way can be used when I have some idea about function name:) I want to obtain list of all functions - don't know function names...

      Then just dump the symbol table of your given package either by hand or using Juerd's Devel::GetSymbols. If you want to roll you own something like this ought do the trick 
      package Foo;

our $VERSION = 0.1;

sub new { bless {}, shift }
sub foo { print "i'm a method of Foo\n" }

package main;

for my $sym (keys %Foo::) {
    print "method - $sym\n" if *{"Foo::$sym"}{CODE};
}

__output__

method - foo
method - new
