Here are some of the various '''containers''' in Tcl:

   [array]:   A container of variables, keyed by name

   [dict]:   The standard key-value store.  Values are ordered by the sequence in which they were set

   [dictionary], by [Frederic Bonnet]:   an implementation of a key-value store, that preceded [dict]

   [list]:   The standard container for sequences of values

   [vector] ([BLT]):   one-dimensional arrays of values

   [TclX] keyed lists:   

   [NAP]:    has some sort of array/vector data structure.
