To add my tuppence-worth on this, addressed to no-one in particular:<div><br></div><div>(1) I think getting hung up on UTF-8 correctness is a distraction here. I can't imagine anyone suggesting that the C/C++ standards removed support for (char*) because it wasn't UTF-8 correct: sure, you'd recommend people use a different type when it matters, but the language standard itself shouldn't be driven by technical issues that don't affect most people most of the time. I'm sure it's good engineering practice to worry about these things, but the standard isn't there to encourage good engineering practice.</div>
<div><br></div><div>(2) I'd suggest that a proposal that advocated overloaded string literals -- of which [Char] was an option -- couldn't be much more confusing from a pedagogical perspective than the fact that numeric literals are overloaded. Since that seems to be one of the main biases in favour of [Char] in the current standard, that might be a possible incremental fix.</div>

</div>As far as I remember, a few functions were added to text and bytestring<br>
during that, but mostly the discussion was about naming.<br>
<br>
Even in the first 0.1 release of bytestring:<br>
<a href="http://hackage.haskell.org/packages/archive/text/0.1/doc/html/Data-Text.html" target="_blank">http://hackage.haskell.org/packages/archive/text/0.1/doc/html/Data-Text.html</a><br>
there is a large amount of Data.List covered, e.g. map, transpose,<br>
foldl1', minimum, mapAccumR, groupBy.<br>
<br>
