Just as simply,

- $foo is the variable 'foo'
- ^foo is the placeholder 'foo'
- $_ is the default variable
- ^_ is the default placeholder

Or any variation, given Nathan Wiger's original list (! ^ &) and others.
Although, I suppose '&' would not work.

I too am having trouble following the current placeholder syntax. :)
