Re: wrong array range with (r) flag on scalar?

yes, but only *after* reading this carefully:
r Reverse subscripting: if this flag is given, the exp is taken as
a pattern and the result is the first matching array element,
substring or word (if the parameter is an array, if it is a
scalar, or if it is a scalar and the `w' flag is given, respec-
tively). The subscript used is the number of the matching ele-
ment, so that pairs of subscripts such as `$foo[(r)??,3]' and
`$foo[(r)??,(r)f*]' are possible if the parameter is not an
associative array.
note: "The subscript used is the number of the matching element".
i would definitely expect a (0-based indexing, pseudocode)
`substr foobar bar` to be 3, not 5.

oh yeah. :)
