So you define Perl5's types as being scalar, array, hash and few others

Right, these are the user exposed types; strings and integers (PV/IV) are hidden from the user as much as possible, so I don't see them as types in Perl 5. (This attitude is influenced by me not writing any XS code, I think).

No, no coercions occur between any of of those types. 
my $scalar = @array;
# or
my @array = $scalar;

Is that no coercion?

Talking of static vs dynamic typing sounds a lot like talking about strong vs weak typing.

In my book there's a difference: For example the C programming language has static typing (determined at compile time), but weak (you can cast anything to anything else even if it doesn't really makes sense).

But I'm guess I use these words not in the same sense as everybody else does, nor is there any shared consensus on what these things actually mean.
