Re: need argument for try catch blocks

  On can get rid of most of the features of OOP (such as

  It would be sufficient to add a few extensions to C:

{ __resource struct example *const e =
  malloc( sizeof( struct example ));
  ... }

  The ?__resource? keyword requests a primitive kind of
  RAII, which is implemented as follows:

  ?struct example? (or whatever other struct used with
  this) must be have been defined as:

struct resource
{ int( *cleanup )( struct resource *resource ); ... }

  , i.e., it must start with a pointer to a function taking
  a pointer to such a struct as an argument.

  The C+RAII compiler will then make sure that this function
  is called upon block exit with the object pointer as an
  argument, whenever the object pointer is not 0.
