huggable Zoffix, say $v.VAR ~~ Scalar|Proxy ?? "conted" !! "deconted"
Zoffix lizmat: that's one way that I know of ^ 11:47
lizmat thought of "it.VAR.^name ne it.^name" 11:52
this also handles IntLexRef 11:54

samcv finally all the tests i wrote for utf16le and utf16be and utf16 and detecting bom with decode stream are passing \o/ 21:58
made sure that .readchars(1) makes sure things don't get unaligned

AlexDaniel lizmat++ 22:15
timotimo lizmat++ 22:20
samcv so on my utf16 testing branch, `utf16` detects encoding based on BOM, if BOM doesn't exist it uses the machine endianess. If set to utf16be and it sees a big endian BOM, the BOM is ommited. likewise for little endian but for LE BOM 22:27
i still really don't like the byte order marker... i think this is a good way to do it. 22:30
Perl 5 will tell me that a character is illegal if i try to decode the BOM in the wrong endianess (which results in a non-character) 22:31
ah looks like perl 5 will follow the spec and not skip the BOM. i kind of like that way since you are able to store all characters in it 22:33
timotimo i wonder if :keepbom should be a little like :!chomp 22:38
a program written by someone who doesn't expect to get utf16 (say, maybe they use a heuristic to figure out the right encoding), they might be surprised about the garbage at the beginning of the file 22:39

samcv i need to see if the noncharacter which is the BOM with endianess reversed is valid in utf16. i mean. you probably shouldn't have it. but if it's not valid period 22:42
though i suppose dying on reversed BOM character is not as bad as utf8 i feel. because there *are* illegal characters in utf16. namely you can't represent the low surrogates or high surrogates in anyway 22:49
TimToady it was intentionally designed to be invalid when reversed, iirc 22:56
and I think has been generalized to every plane, such that the *fffe and *ffff are considered invalid 22:57
samcv yeah it has TimToady
this whole thing is so messy though!
TimToady an aBOMination :) 22:58

MasterDuke timotimo: did you see my comments in #moarvm last night? i figured out what that error i was getting was from 23:32
timotimo oh, was it a typo'd class name? 23:33
MasterDuke QAST::Something() vs QAST::Something.new() 23:34
timotimo i should have been able to spot that :\ 23:35
MasterDuke and then i also had a QAST::WVar instead of QAST::WVal
the sad thing is it's not the first or even second time i've done that and gone on a long goose chase before realizing what the real problem was
timotimo yeah :| 23:36
i've very briefly looked into making that a compile-time error
i didn't get it working, and it's been so long ago that i don't know any more what was up
MasterDuke i know there's less interest in nqp errors, but wow, i've lost some time to them 23:38
