Lisp macros and first-class lambdas. In all three languages.
A construct that allows explicit transfer of control to another
statement in order to create control structures more complex than
if-then-else or while-do. Call it "past", e.g.
try
{
a:
process();
}
catch (Exception ex)
{
log(ex);
reinit();
past a; // i.e. transfer control to the statement just past
the label a
}
A method which uses this construct can be called "past a" code.
Hmmm. This seems to carry a risk of coming close to arbitrary goto, and
hiding a loop.
I would code it with an explicit loop as:
boolean done = false;
while(!done)
{
try
{
process();
done = true;
}
catch (Exception ex)
{
log(ex);
reinit();
}
}
In practice, I would also put a limit on the number of retries, and take
more drastic action if it is exceeded.
Anyone have a smoother idiom for this one?
