If a blessed hash reference has a key foo and a method foo, TT will
defer to the method call. This is in keeping with the design pattern of
encapsulation. The rationale is that you may want to change the
underlying implementation of the class, such that $obj->{foo} is moved
to $obj->{foo}{main} to distinguish it from, say, $obj->{foo}{special}.

Hi all,=20

Suppose an object $obj has both a hash entry $obj->{foo} and a method
$obj->foo().=20

If I pass this object to a template,  [% obj.foo %] performs a method
call.=20

 Is there a way to access the hash entry instead?=20

Thanks in advance, L. Dami=20
