Use of lambda

[Chris Maden <crism@xxxxxxx>]

I'm cleaning up my SGML->MIF stylesheets; hopefully they'll be in a
state where I won't be embarrassed to share them soon.

For a few parameters, I had needed functions to dynamically build a
string.  Rather than having some variables and some procedures
arbitrarily, I've made them all variables, but defined some with
lambda.

For instance:

(define pages
  (lambda ()
    (string-append "...")))

When I call this in the stylesheet:

(string-append "..."
	       pages
	       "...")

the function is processed.  Is it kosher to call a no-argument
function without any parentheses, or is Jade being forgiving?  Should
I go the other way and make everything a procedure instead of a
variable, and just define some of those procedures as always giving
the same results?

Thanks in advance,
Chris
