Usage of ～やら～やら vs ～や～や


What is the conceptual difference, or difference in nuance between these two
constructions when used to mean 'and'? I realize there are some syntactic
differences, such as や not appearing after the final item being enumerated,
but as far as general nuance is concerned, is there any significant
difference? For example, here's a couple sentences:

1a. 怪我 **やら** インフルエンザ **やら** で、試合に出られない選手が多い。

1b. 怪我 **や** インフルエンザで、試合に出られない選手が多い。

2a. 今日は会議 **やら** 新人研参会 **やら** があって無理。明日なら大丈夫だけど。

2b. 今日は会議 **や** 新人研参会があって無理。明日なら大丈夫だけど。

Is there any difference in meaning in these (or perhaps other) examples of
usage?




や is often taught as a non-exhaustive connective. When you say AやB, you mean
that there may be a C, but you didn't mention it (for example, you could say
"ロックのCDやジャズのCDを買いました" because maybe you bought doughnuts too (but who cares?);
but you wouldn't say "部屋には男性や女性がいます" since there is not other choice.)

As far as I remember, やら expresses some kind of disorder in your listing. It
is also non-exhaustive, but it puts emphasis on the variety of elements. You'd
use it to say "hipsters, bums, rockstars and politicians, everyone wanted to
go to my sweet 16."

Examples of usage will be found it the great google corpus :)
