Jade - tags and plain text in one string

I've started using Jade few days ago. Now I've got a simple question (briefy looked though Jade docs - couldn't find an answer).

h2 Welcome! Please, a(href="/login") log in.

generates plain text. How can I make Jade process

a(href="/login") log in

as a Jade-styled html tag? Thanks!

You have to put it on a new line, tabbed inside the element:

h2 Welcome! Please, 
  a(href="/login") log in.
