Though Ton is not of this earth, the @{[...]} idiom is.
(I think Larry plans to clean it up for Perl 6, however).
I knew about it long before I swung my first club.
I learnt about by reading the Camel (p. 259, "Other Tricks
You Can Do With Hard References", Chapter 8) and from
"Effective Perl Programming", Item 58 "Use @{[...]} or
a tied hash to evaluate expressions inside strings".
Curiously, Joseph N. Hall (who is a keen real golfer)
uses a golf example to explain it on p. 240:
print "I'm @{[$golfer->name]}\n"; I'm Tiger Woods
Here is another reference to where this trick was used
in a golf game:
