These are type-checking array objects; elements are checked against the
specified type when the object is constructed or new elements are added.
.PP
The first argument passed to the constructor should be a Type::Tiny type:
.PP
.Vb 2
\&  use Types::Standard \-all;
\&  my $arr = array_of Str() => qw/foo bar baz/;
.Ve
.PP
If the initial type-check fails, a coercion is attempted.
