40 ## Get the list of codepoints for the type.
41 ## Called from swash_init (see utf8.c) or SWASHNEW itself.
42 ##
43 ## Callers of swash_init:
44 ## op.c:pmtrans -- for tr/// and y///
45 ## regexec.c:regclass_swash -- for /[]/, \p, and \P
46 ## utf8.c:is_utf8_common -- for common Unicode properties
47 ## utf8.c:to_utf8_case -- for lc, uc, ucfirst, etc. and //i
48 ##
49 ## Given a $type, our goal is to fill $list with the set of codepoint
50 ## ranges. If $type is false, $list passed is used.
51 ##
52 ## $minbits:
53 ## For binary properties, $minbits must be 1.
54 ## For character mappings (case and transliteration), $minbits must
55 ## be a number except 1.
56 ##
57 ## $list (or that filled according to $type):
58 ## Refer to perlunicode.pod, "User-Defined Character Properties."
59 ##
60 ## For binary properties, only characters with the property value
61 ## of True should be listed. The 3rd column, if any, will be ignored
62 ##
63 ## $none is undocumented, so I'm (khw) trying to do some documentation
64 ## of it now. It appears to be if there is a mapping in an input file
65 ## that maps to 'XXXX', then that is replaced by $none+1, expressed in
66 ## hexadecimal. The only place I found it possibly used was in
67 ## S_pmtrans in op.c.

69 ## To make the parsing of $type clear, this code takes the a rather
70 ## unorthodox approach of last'ing out of the block once we have the
71 ## info we need. Were this to be a subroutine, the 'last' would just
72 ## be a 'return'.
