"GNU Emacs 21.2.1 (i386-msvc-nt5.0.2195) of 2002-03-19 on buffy"
1) M-x cperl-mode
2) load-library align
3) Write the above tests
align.el behaves incorrectly in cperl-mode where the code reads:
%hash = ( one => 1
, amnMore => 2
, hm => 3
, likeThisOne => 4-!-
);
Position cursor (-!-) anywhere at the end of the above lines and
call M-x align-newline-and-indent. The problem is that align.el
seeks first "=":
%hash = ( one => 1
, amnMore => 2
, hm => 3
, likeThisOne => 4
);
It should be smarter and align according to "=>". I studied the
code, but I do not undertand the syntax rules used there enough to
make any suggestions.
%hash = ( one => 1
, andMore => 2
, hm => 3
, likeThisOne => 4
);

Align is not smart enough to maintain "state", and thus make
intelligent decisions about alignment priority, or what should and
what shouldn't be aligned. These are just line-by-line regexps,
after all.
In cases like this where is definite confusion, you, the human, will
have to step in. Simply type M-x align-regexp on the region, and
then type "=>". This will do exactly what you want.
