The names of already defined token can be used for the definition of other token. To do this, the name must be included into the braces '{' and '}'. Now this expression can be situated inside of a new token definition. When parsing the new definition, the TextTransformer will remove the braces and substitute the token name by its text.

Example:

SPACES = [ \t]*

DECLARATOR =

(((\w+::)*\w+)::)?(\w+) \ //Scope(s) and name

{SPACES} \                // optional spaces

\([^)]*\)                        // Parameter

Internally the TextTransformer will collapse the line to one:

(\w+::)?(\w+)::(\w+)[ \t]*\([^)]*\)
