ARF has a collection of basic control flow phrases which are break, next,
and return. Break breaks out of a loop or switch case, next is basically just
a continue statement but using less letters, and a return phrase returns from
the current function. Return phrases are entirely optional and do not take any
arguments.
ARF also has some control flow phrases that expect an indented block of phrases under them:
if condition
something
if condition
something
else
otherThing
while condition
something
switch value
: 324
something
: 93284
otherThing
:
defaultThing
for index:Size element:Int someArray
something
These do what you'd expect them to, but for loops in ARF need some further
explanation. Many modern languages allow you to iterate over data, and ARF is no
exception. The first argument of a for loop must be an index of type Size, the
second argument must be typed as an element of the third argument, which must
be an array or inherit from an array. In the future there might be some
iterateable interface that an object could fulfil.
