1 Version 0.03 of the new Glasgow Haskell compiler was an unannounced
2 (exceedingly unpolished) release for our friends at York.
4 -------------------------------------
6 A quick list of things to note:
8 * Significantly different parser (parsers/hsp/) and reader
9 (compiler/reader/), to do Haskell 1.1 syntax. The abstract syntax
10 (compiler/abstractSyn/) now covers the entire Haskell language.
12 * Compiler files have been majorly shuffled, renamed, in part to
13 ensure filenames are <= 14 chars. Another such catastrophic
14 re-shuffle is unlikely for the foreseeable future.
16 The file docs/FILE-RENAMING is a fairly complete list of
19 * Pretty-printing machinery (compiler/utils/{Pretty,Outputable}.lhs)
20 is completely changed.
22 * Identifiers are now "Ids" (compiler/basicTypes/Id.lhs), not "Locals"
25 * What-the-compiler-must-know-about-the-prelude (compiler/prelude) is
26 believed to be complete; this includes Chars, Ints, Floats, and
27 Doubles as primitives.
29 (Stuff for Integers and Rationals is NOT all there.)
31 All other prelude stuff should be specifiable w/ an ordinary
32 interface file (notably lib/prelude/MiniPrel.hi).
34 * The compiler does full-blown overloading of expressions and
35 patterns. Yell if this really won't do -- perhaps a build-time
38 * All flavours of patterns and expressions (e.g., n+k patterns,
39 arithmetic sequences) are in; testing in some cases near zero.
41 * BUGS INEVITABLE, MAJOR BUGS ENTIRELY POSSIBLE, PATCHES WILL PROBABLY
42 BE REQUIRED. Don't panic, report promptly!
44 * "main"'s (main/Main.lhs) handling of command-line options [and the
45 feeding of same by the driver, driver/ghc.lprl] has been revised.
47 * Documentation has _not_ been updated.
