All { braces must have a matching } brace. This scene just puts the 
opening braces in the macro, and the closing braces after the calls to 
that macro. Cleanly indented, the code's a lot easier to understand:

#macro C()
    function {
        pigment {crackle
#end

#local A = C() solid}}

#local B = C() }}

This is equivalent to:

#local A = function {pigment {crackle solid}}

#local B = function {pigment {crackle}}
