On Topic (O'Reilly)
Allison Randal
delves into the Perl "topics" on O'Reilly.
"A few concepts in Perl 6 are strange at first sight. They seem hard to understand, but it's only because they're new and different. They aren't deep mystical concepts known only to Tibetan lamas. Anyone can understand them, but it helps to start with a common-sense explanation.
This article looks at the concepts of "topic" and "topicalizer". The words aren't quotes from a particularly nasty bit of Vogon poetry. They're actually common terms from the field of linguistics ... which some might say is even worse. Still, the best way to understand topic in Perl is to understand its source."
