Then let it hereby be known that flexible-size arrays, mixed-type arrays
and dictionaries have joined the master branch on November 25th. ;)

Also included are two pseudo-dictionaries, `local` and `global`,
representing the "most local" identifiers and the global identifiers,
respectively. For example:

    #declare local.Foo = 4711;
    #undef global.Foo;

will declare a local variable named "Foo", and undefine any global
variable of the same name, respectively.

*NOTE*: These pseudo-dictionaries *REPLACE* the `local()` and `global()`
pseudo-functions, which are currently mentioned in the tutorial's "New
features" section, the "Identifier Name Collisions" section in the
reference page on #declare and #local, and in the "Optional Parameters"
section in the reference page on macros.
