val optimizeHandlers: bool option
Exception handlers are optimized on subsequent compilations if optimizeHandlers is true. The stack may or may not be unwound by exception handlers before executing. It is more efficient if the stack is unwound, but information is lost if the stack browser is entered. If optimizeHandlers is true, then exception handlers unwind the stack, otherwise they do not and the stack is preserved for debugging purposes.
