Yes, the \begin{foo} … \end{foo} syntax. Technically, an environment means that 
variables are stacked in a syntactically local group, as in \begingroup … 
\endgroup.

The syntax in the example file is «foo· … ·» or «foo· … ·foo», so one does not 
have to write the ‘start' and ‘stop’ all the time, and does not have to write 
the name of the environment again at the end.

I think this corresponds (in pseudocode) to my
\new{Environment}{typing}%
  {}{<before code>}%
  {<after code>}{}

In LaTeX, if I remember correctly, it would expand to \begingroup<before code> 
… <after code>\endgroup.

I added so one can have 
\new{Environment}{typing}%
  {<before code>}{<begin code>}%
  {<end code>}{<after code>}
expanding to
  <before code>\begingroup<begin code> … <end code>\endgroup<after code>

So one has more control over designing the environment. One can then also 
define a new environment
\new{Environment}{typingmore}%
  {<code>}{<code>«typing·<args>}%
  {·typing»<code>}{<code>}
I think, to make specializations.

It looks like just adding a series of command names, rather than a stacked 
environment, or a namespace (module). If one wants to avoid name clashes, one 
can have names like in directory names, living without any local group.
