| #" ... "# | Liberal String | S | 
|  | Allows for the easy specification of strings (especially C code
  snippets) with special character escaping turned off. |  | 
| C-MENT | (C-MENT [,c-snippet ,goo-form]*) | S | 
|  | Specifies a C statement formed as the
  concatenation of c-snippets (goo strings) and
  GOO forms 2.  
  The GOO forms are evaluated at runtime as embedded C expressions in the
  lexical context of the c-ment expression.
  If specified at top level, then the c-ment form 
  will be evaluated prior to the
  evaluation of non c-ment top level forms. |  | 
| C-EXPR | (C-EXPR [,c-snippet ,goo-form]*) | S | 
|  | Same as c-ment but specifies a value producing C
  expression instead. |  | 
| to-c | (x) | G | 
|  | user extensible protocol for converting a GOO object to a C
  value.  Methods are provided for <int>, <flo>,
  <str>, <chr>, <log>, and <loc>. |  | 
| #{ ... } | Inlined C Statement | S | 
|  | Shorthand for c-ment allowing GOO forms to be
  specified with a $ prefix and the conversion of GOO
  objects into C values specified with an
  @ prefix, with @x  ==  $(to-c x).
For example, 
(df f (x) #{ printf("Got %lx", $x); })
prints out the GOO value x.  
A callback can be defined at top level as follows:
#{ int gl_idle(int x) { $(gl-idle); } }
C headers can be included similarly:
#{ #include "GL.h" }
C expressions can be nested within embedded GOO expressions as follows:
#{ int gl_idle(int x) { $(gl-idle #ei{ x }); } }
in order to access lexical apparent C variables etc. |  | 
| #ec{ ... } | Inlined C Expression | S | 
|  | Similar shorthand for c-expr also allowing a single
  character code c for specifying the conversion of C values back to
  GOO objects.  The valid codes are i for <int>, 
  f for <flo>, s for <str>, 
  c for <chr>, b for <log>, 
  l for <loc>, g for none.
For example, 
(d. $gl-line-loop #ei{ GL_LINE_LOOP })
defines a top-level OpenGL constant. |  | 
| USE/LIBRARY | (USE/LIBRARY ,name) | S | 
|  | adds ,name to list of libraries to be linked against. |  | 
| USE/INCLUDE | (USE/INCLUDE ,name) | S | 
|  | adds ,name to include directory search path. |  |
