in reply to How I Learned About Quines

As a side note to your nice explanation: You are free to choose the ordering of code and data (encoding). If you start from code+data (opposed to data+code), you'll get a functional programming style quine, like this:

sub{print qq[sub{print qq[$_[0]]}->(q[$_[0]])]}->(q[sub{print qq[$_[0] +]}->(q[$_[0]])])

In a digestible form (but this way it screws up the whitespaces):

sub { print qq[ sub { print qq[ $_[0] ] }->( q[ $_[0] ] ) ] }->( q[ sub { print qq[ $_[0] ] }->( q[ $_[0] ] ) ] )

Sorry for the parentheses haters.

    very nice! sorry, couldn't resist to shorten it:

    sub{print"@_->(q(@_))"}->(q(sub{print"@_->(q(@_))"}))
