I should have put quotes around my statement. For as long as you
refuse to use the means which are available to you in order to deal
with technical problems you happen to have, these technical problems
will continue to bite you. Similar to 'modifiable function pointers'
being a more general runtime binding facility than 'virtual method
tables', setjmp/ longjmp are a more general facility for designing
subroutines with more than one exit point (this refers to 'location
control will be transferred to after the subroutine stopped executing'
not to 'number and placement of return statements inside a subroutine)
than so-called 'exceptions'. Among other things, they can be used to
handle otherwise fatal hardware exceptions by transfering control to
some other place than the unexecutable instruction which caused the
exception. With some amount of effort, you could presumably also patch
the machine code at runtime instead :->
