2.2 Pragmas for Controlling Compilation
optimize and no_optimize pragmas enable and disable, respectively, compilation of a method with optimization.
debug pragma on a method disables optimizations like static binding and inlining that would prevent the method from being replaced by the evaluator or caught by a breakpoint.
inline and no_inline pragmas specify that the annotated method should be inlined or not inlined, respectively, when statically bound. (If no such pragma is present, an automatic inlining heuristic is used.)
no_typecheck pragma on a method disables typechecking of the annotated method.
Specifying any of these pragmas at the top-level of a file affects all methods declared in the file.
