for bla bla else bla bla
Ever written something like this?:
found = false
for i in list
if i == wanted
found = true
do_something()
break
if not found
do_something_else()
In Python there is a nice construction that makes this much easier - the for else statement. The same code in Python can be written as:
for i in list:
if i == wanted:
do_something()
break
else:
do_something_else()
The else-statement is executed if the for-loop is terminated by exhaustion of the list. Pretty neat. Is this available in any other language?

Mmmm...
I think what you want is an archaic language known as BaySick. It was very popular among the early so-called High-level Language Programming-in-my-bedroom officianados back in the mid-eighties.
The story of BaySick's rise and fall is a tortuous and tragic one, but the denoument is widely agreed to be centred around the now infamous "GOTO" construct. For all its glory, failings and leaps into the deep-blue of uninitialised memory, you could do this:
I=0
LOOP:
PRINT "DO-SOMETHING"
IF FOUND GOTO OBLIVION
I=I+1
IF I>10 GOTO OVER:
GOTO LOOP
OVER:
PRINT "MORE PROGRAM"
GOTO END
OBLIVION:
PRINT "NOT SO SHABBY HUH"
END:

The wonderful world of ruby:
if list.include? i
do_something
else
do_something_else
end
kinda cheating, but cool.
