Current 3.7 release. Small thing, but happened to notice a couple 
missing back slashes in the debug statements at the bottom of the 
example code in section 3.3.1.8.2.

---------------------------
3.3.1.8.2 Functions and Macros

...

You can pass functions to macros, how to do this is best explained by an 
example:

#macro Foo( Bar, X )
#declare Y = Bar(X);
#declare Z = Bar(Y);
#end

#declare FUNC=function(n){n+2}

Foo(FUNC, 1)

#debug str(Y,5,5)
#debug "n"
#debug str(Z,5,5)
#debug "n"
----------------------------

Those two '#debug "n"' lines should I believe read '#debug "\n"'.
