Yes, it's a convenience method, like 'dot' and 'underscore'. The code I
pasted is from the unit tests, where I use the different methods to push
coverage up.

Nope, they're synonyms. Same as 'zero_or_more' is the same as
'any_number_of', or 'digit' is the same as 'digits'.
Why do some things have __ in front of them? Is there a

Er... looks like a garblement in my post! There are no __ in my original
:( It should be:
north_american_number_re = (RE().start
.literal('(').followed_by.exactly(3).digits.then.literal(')')
.then.one.literal("-").then.exactly(3).digits
.then.one.dash.followed_by.exactly(4).digits.then.end
.as_string())
Thanks for the comments!
