-APL mode
-
-
-
-
- Simple mode that tries to handle APL as well as it can.
- It attempts to label functions/operators based upon
- monadic/dyadic usage (but this is far from fully fleshed out).
- This means there are meaningful classnames so hover states can
- have popups etc.
-
- MIME types defined: text/apl
(APL code)

- This loop is a "comment loop", it's a simple way of adding a comment

- /** A template trait for traversable collections of type `Traversable[A]`.
- *
- * $traversableInfo
- * @define mutability
- * @define traversableInfo
- * This is a base trait of all kinds of $mutability Scala collections. It
- * implements the behavior common to all collections, in terms of a method
- * `foreach` with signature:
- * {{{
- * def foreach[U](f: Elem => U): Unit
- * }}}
- * Collection classes mixing in this trait provide a concrete
- * `foreach` method which traverses all the
- * elements contained in the collection, applying a given function to each.
- * They also need to provide a method `newBuilder`
- * which creates a builder for collections of the same kind.
- *
- * A traversable class might or might not have two properties: strictness
- * and orderedness. Neither is represented as a type.
- *
- * The instances of a strict collection class have all their elements
- * computed before they can be used as values. By contrast, instances of
- * a non-strict collection class may defer computation of some of their
- * elements until after the instance is available as a value.
- * A typical example of a non-strict collection class is a
- *
- * `scala.collection.immutable.Stream` .
- * A more general class of examples are `TraversableViews`.
- *
- * If a collection is an instance of an ordered collection class, traversing
- * its elements with `foreach` will always visit elements in the
- * same order, even for different runs of the program. If the class is not
- * ordered, `foreach` can visit elements in different orders for
- * different runs (but it will keep the same order in the same run).'
- *
- * A typical example of a collection class which is not ordered is a
- * `HashMap` of objects. The traversal order for hash maps will
- * depend on the hash codes of its elements, and these hash codes might
- * differ from one run to the next. By contrast, a `LinkedHashMap`
- * is ordered because it's `foreach` method visits elements in the
- * order they were inserted into the `HashMap`.
- *

- * @tparam Repr the type of the actual collection containing the elements.

-# Features of Crystal
-# - Ruby-inspired syntax.
-# - Statically type-checked but without having to specify the type of variables or method arguments.
-# - Be able to call C code by writing bindings to it in Crystal.
-# - Have compile-time evaluation and generation of code, to avoid boilerplate code.
-# - Compile to efficient native code.
