1017	recognize the <a b c> form of alternation	coke	pmichaud	"[http://rt.perl.org/rt3/Ticket/Display.html?id=51850 Original report].

Original Post:
{{{
A <?before> rule with a space between the '<' and the '?' compiles
but fails at execution
with the unhelpful message :
Unable to find regex ''
Null PMC access in invoke()

-- 
cognominal stef
}}}

Followup:
{{{
I agree that this is not a useful error message. However, when
PGE is corrected to follow the specification the regex

< ?before foo>

would be identical to

'?before' | 'foo'

and no error message would be generated at all. 

(PGE hasn't been updated to recognize the < a b c > form of
alternation.)
