## Tutorial
GTWIWTG is a tiny library for creating and using generators.
@@ -289,23 +261,6 @@ Here are some simple examples of their use:
intermingles the values of its argument generators, in the order
they appear in the argument list.
-And some experimental tools:
-
-- `(nfurcate! n gen)` returns a list of `n` new generators, each
- producing the same elements as of `gen`.
-- `(partition! pred gen)` returns a list of two new generators, the
- first generating the memebers of `gen` that pass the predicate
- `pred`, and the second generating those that don't.
-- `(disperse! n gen)` is sort of the opposite of
- `intersperse!`. Returns a list of `n` generators, the first produces
- every nth value from `gen`, the second produces every nth+1 values
- from `gen`, and so on.
-
-The above are marked as EXPERIMENTAL because they may not be
-in line with the the spirit of this library. I wanted the library to
-produce constant-memory operations. However, when you consume the
-generators that the above forms produce, then new memory will be
-consed during consumption. See the docstrings for both forms for more details.
