Part of the thinking behind this is that the <[...]> construct
is likely to be less common in p6 rules than [...] was in p5 regular
expressions. For unicode reasons, one typically should be writing
<alpha> instead of <[a-z]> anyway.
But yes, I understand the difficulty of typing <[...]> on non-US
keyboards. :-)

Actually, \L[...] is gone -- see S05 and A05. I'm not sure if \a
exists, I haven't seen any reference to it in p6 rules. (One could
claim that it's carried over from p5, but rules are so far different
from regexes that I'm hesitant to make that assumption.) We could
certainly declare \a to be something else.
This isn't a vote from me either in favor or against this idea...
I'm just clarifying and making sure the discussion is up-to-date
with the relevant specs.
