2011-11-07	EEP-23: Allow variables in fun M:F/A	Björn Gustavsson
	Currently, the external fun syntax "fun M:F/A" only supports literals. That is, "fun lists:reverse/1" is allowed but not "fun M:F/A". In many real-life situations, some or all of M, F, A are not known until run-time, and one is forced to either use the undocumented erlang:make_fun/3 BIF or to use a "tuple fun" (which is deprecated). EEP-23 suggests that the parser (erl_parse) should immediately transform "fun M:F/A" to "erlang:make_fun(M, F, A)". We have not followed that approach in this implementation, because we want the abstract code to mirror the source code as closely as possible, and we also consider erlang:make_fun/3 to be an implementation detail that we might want to remove in the future. Instead, we will change the abstract format for "fun M:F/A" (in a way that is not backwards compatible), and while we are at it, we will move the translation from "fun M:F/A" to "erlang:make_fun(M, F, A)" from sys_pre_expand down to the v3_core pass. We will also update the debugger and xref to use the new format. We did consider making the abstract format backward compatible if no variables were used in the fun, but decided against it. Keeping it backward compatible would mean that there would be different abstract formats for the no-variable and variable case, and tools would have to handle both formats, probably forever.

2011-05-12	Types and specifications have been modified and added	Hans Bolinder

2011-03-22	Fix a bug concerning record field types	Hans Bolinder
	The default value 'undefined' was added to records field types in such a way that the result was not always a well-formed type. This bug has been fixed. --- erl_pp has since OTP-8150 formatted types so that 'undefined' was removed from union types assigned to record fields. Since one cannot distinguish between 'undefined' added by the parser or supplied by the user, a side effect was that user supplied 'undefined's were also removed. Now the pretty printer shows 'undefined' even if added by the parser. This is a minor issue.
2010-06-02	OTP-8664 Erlang parser augmented with operators for integer types	Hans Bolinder
	Expressions evaluating to integers can now be used in types and function specifications where hitherto only integers were allowed ("Erlang_Integer").
2010-03-09	OTP-8501 stdlib: erl_pp no longer quotes atoms in types	Hans Bolinder
	The erlang pretty printer (erl_pp) no longer quotes atoms in types.
2010-03-02	OTP-8473 stdlib: erl_pp bugfix abstract type 'fun'	Hans Bolinder
	The abstract type 'fun' could not be printed. This bug has been fixed.
