Ordinarily I would agree with you. But I know my own brain and
how it works. I only learn by doing. Have tried to change that
and can't.
A good tutorial book *will* make you "do." The brian d foy book does
exactly that with things to try, and questions to explore in your own
code. It takes
The signatures in the docs are often the exact same signatures
as the code they are documenting.

With perl5 code, I've gravitated to talking about "routines" when I don't
want to worry about whether something is technically a function or a
method. It doesn't seem to confuse anyone. (On the other hand, I've had
people make fun of me for using the word "subroutine",

Basically, ignore any advice to treat Nil as a normal value, because
it really is intended to represent the *absence* of a value as much as
possible. It's a bit like the way solid-state electronics treats "holes"
as if they were real particles, and gets away with it much of the time.
But not all t
Neat. The answer's round about right.

Just for giggles, say e**(i*pi) + 1 prints 0+1.2246467991473532e-16i
which isn't exactly right, but close enough for government work.
(You could call it really right, the error is imaginary. :-)* )

Pi and tau can also be accessed as the Unicode characters.

When you assign Nil to a string or any object, it takes its default value.

If you don't define the type of a Scalar and don't assign to it you'll have
an undefined Any (the Parent class of all the other types). If you assign
Nil to it then you have the same effect.
You can make $x to be Nil by iether casting it : my Nil $x; or binding it
to Nil; my $x; $x := Nil;
