[01:01] <harmil> I'm not sure how to read this error: Only identical
operators may be list associative; since '..' and '..' differ, they are

[01:05] <TimToady> it's LTA for sure
[01:06] <TimToady> .. should really be considered non-associative, probably
[01:06] <harmil> TimToady: Great example. I'll rakudobug that before I turn

[01:06] <TimToady> m: 1 but 2 but 3

[01:07] <TimToady> yeah, non-associatives are somehow getting treated as
list associatives
[01:07] <TimToady> m: say 1 <=> 2 <=> 3

[01:07] <TimToady> it's just the wrong error
