No worries! =) Let me clarify the relation between Transducers and

The basic component in the framework is the so-called ReducingFunction.
This are functions that take two arguments, an 'intermediate value' and a
'current element', and map them to a new intermediate value,
Solutions to different problems.
I proposed a simple generic thing that only composes functions, allowing for
transformation of block arg.
Transducers seem like streaming, data-flow specific, thing.
Maybe yours helps the original problem in the long run.
I just tried to find something to
I think, streams and functional composition match up nicely and
transducers are a way to do this. I've introduced them earlier on this
list. (I hesitated to weight into the discussion, as I won't have time to
work on the Pharo port of Transducers until October.)
Let me give a simplified

Experience with Java taught me to loath ethe "do I/O
by composing lots of little wrappers" approach for
several reasons:
- the fact that the commonest case was not the
default case, so that simple obvious code was
somewhere between disgracefully slow and wrong
- the extra complexity needed

Hi,
I'm starting to familiarize myself with new streams, and one thing I've
noticed is the removal of #lineEndConvention (which I use all the time).
So a statement like this
aFile writeStreamDo: [ :stream |
stream lineEndConvention: #lf.
stream << '...'
].
has to be written like so
aFile
