The documentation implies that the pointer escaping the scope and calling the
function is safe as long as it does not access a variable of the enclosing
function that went out of scope.

Actually that is not valid as func is local to that scope and now it escapes.

There is also the Apple blocks extension to C.

For the record, this is already possible using bracketed expressions, but the
syntactical sugar of not having to pick a function name would be great.

#include 
#include 

int
main (int argc, char **argv)
{
  void (*func_ptr)(int) = ({ void func(int i) { printf ("%i\n", i); };
 func;
   });

  func_ptr (3);

  return EXIT_SUCCESS;
}

There obviously is some relation, but this proposal evades syntactical
overloading of operators, unlike C++ lambda functions or LLVM blocks.

This sounds like C++ lambda functions.

Second,  I think this is a bad idea for C.
