Yes, they would be separate. Their names would be mangled so they don't overlap when the program is linked -- the same way all C++ variable and function names get mangled so they don't overlap, to allow overloading.

In the case above, wouldnt it create a global Egg e, which also contains another global Egg e
I suppose there would be an Egg:e.e inside ( not Egg::Egg::e ) as well as Egg::e.e.e, and so forth. But they'd all be the same object -- not a different one. They're not really contained inside the class in the first place, so they don't nest. Just consider them globals with funny names.

ppi::token::quotelike
PPI::Token::QuoteLike(3) User Contributed Perl Documentation PPI::Token::QuoteLike(3)
NAME
PPI::Token::QuoteLike - Quote-like operator abstract base class
INHERITANCE
PPI::Token::QuoteLike
isa PPI::Token
isa PPI::Element
DESCRIPTION
The "PPI::Token::QuoteLike" class is never instantiated, and simply provides a common abstract base class for the five quote-like operator
classes. In PPI, a "quote-like" is the set of quote-like things that exclude the string quotes and regular expressions.
The subclasses of "PPI::Token::QuoteLike" are:
qw{} - PPI::Token::QuoteLike::Words
`` - PPI::Token::QuoteLike::Backtick
qx{} - PPI::Token::QuoteLike::Command
qr// - PPI::Token::QuoteLike::Regexp
<FOO> - PPI::Token::QuoteLike::Readline
The names are hopefully obvious enough not to have to explain what each class is. See their pages for more details.
You may note that the backtick and command quote-like are treated separately, even though they do the same thing. This is intentional, as
the inherit from and are processed by two different parts of the PPI's quote engine.
