Sorry all, for not being too descriptive.. The closest I want to accomplish is the this example u shown :

my %map = (
    typeA => sub { $_[0]->{key1}[3]{key2} },
    typeB => sub { $_[0]->{key3} },
    typeC => sub { $_[0]->[1]{key4} },
    # ...
);

i.e. in my concentrate case I was looping over a result of SOAP::Lite. Which depending on the type of the object places the 'price' in different places f.e.

$$obj{cost}  <--type1
$$obj{priceList}{price}  <--type2
$$obj{priceList}{price}{value}  <--type3
...etc..

So instead of doing alot of if-typeX, I thought it will be good if I can store the access-path in some way and do a simple hash lookup.
Is it more clear now ;)
(Something like XPath on LoL)

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
