[shmem]: Discipulus: the <<>> operator is quite new, it is in perl5.24 for instance
[Discipulus]: ah! thanks shmem it works in strawberry 5.24
[shmem]: ah. Introduced in 5.22.0, see perl5220delta
[Discipulus]: if so the previous error is a bit misleading, anyway
[shmem]: well, previous to that << was always treated as the left-shift operator
[Eily]: or the here-doc operator
[Eily]: which is actually how it is parsed in this case
[shmem]: older versions of perl can't guess that "use of <<>> may be implemented someday" :D
Discipulus how much wise my brothers are? ;=)
