There are also the celebrity tabloids, the "Teach Yourself "... "In 24 hours" authors, and whoever's writing the majority of the morning TV news programs. Maybe it's time someone made a bunch of money off of BS on technical and pseudotechnical babble (I mean besides the aforementioned awful programming tutorials and Slashdot).

No such conversion is needed in more functional languages, as already argued above by Daniel Spiewak. @Cody Koeninger: you missed the discussed point – you are still doing a conversion, when you type:

Likewise there's no difference between a scalar holding a reference to a lambda and a scalar holding a reference to a function. users-computer:~ user$ perl -d -e 42 DB sub function { print("called a function\n") } DB $function = \&function DB $lambda = sub { print("called a lambda\n") } DB *lambda = $lambda DB function() called a function DB lambda() called a lambda DB $function->() called a function DB $lambda->() called a lambda I don't see any difference in invocation syntax there. If you want to write all of your subroutine definitions as *bar = sub { print("bar") } you're welcome to.

users-computer:~ user$ perl -d -e 42
DB sub function { print(“called a function\n”) }

DB $function = \&function

DB $lambda = sub { print(“called a lambda\n”) }

DB *lambda = $lambda

DB function()
called a function

DB lambda()
called a lambda

DB $function->()
called a function

DB $lambda->()
called a lambda

I don’t see any difference in invocation syntax there. If you want to write all of your subroutine definitions as

*bar = sub { print(“bar”) }

you’re welcome to.
