Ignore-this: 5a178a7f2222293c5ee0c3c43bd1b625
The performance bug in #3245 was caused by computing the typeRep
once for each call of typeOf, rather than once for each dictionary
contruction. (Computing TypeReps is reasonably expensive, because
of the hash-consing machinery.)
This is readily fixed by putting the TypeRep construction outside
the lambda. (Arguably GHC might have worked that out itself,
but it involves floating something between a type lambda and a
value lambda, which GHC doesn't currently do. If it happens a lot
we could fix that.)

Simon Marlow <[email protected]>**20091012152955
Ignore-this: 9f7a7176193eab25c9daaacd9261f2de
Strictly speaking this breaks Haskell 98 compatibility, which requires
hGetContents to just end the lazy stream silently if an error is
encountered. However, for a few reasons we think it will make
everyone's life a bit easier if we make this change
1. Errors will be a lot more common in GHC 6.12.1, in the form
of Unicode decoding errors.
2. When Haskell 98 was designed, we didn't know how to throw
exceptions from inside lazy I/O, but now we do.
3. If anyone is actually relying on the previous behaviour, their
code is arguably broken.

Storing the lookup tables adds about 40KB to each statically linked executable;
this only increases the size of a "hello world" program by about 7%.
Currently we do not support double-byte encodings (Chinese/Japanese/Korean),
since
including those codepages would increase the table size to 400KB. It will be
straightforward to implement them once the work on library DLLs is finished.

clients using Control.OldException will be unaffected (the new
exceptions are mapped to the old names). However, for base4-compat
we'll need to make a version of catch/try that does a similar
mapping.
