It can be interpreted as an array-ish structure that takes strings as
indices:

    #declare Foo = dictionary;
    #declare Foo["Some Index"] = 4711;

As syntactic sugar, if an index satisfies the rules for an identifier,
the index can also be written using dot notation; for example, the
following two lines are equivalent:

    #declare Foo["Bar"] = 815;
    #declare Foo.Bar = 815;

With this notation in mind, a dictionary can also be interpreted as what
would be called a "struct" in C/C++ or a "record" in Pascal - or as a
namespace, which is pretty much what it actually is under the hood.


The future plan is to also extend dictionaries to be able to hold
macros, which would make them usable for object-oriented programming.
But that still needs a bit of work.
