-=head1 Constraint
-X<|Constraint>
-
-Constraints are a restriction placed on acceptable types for a parameter
-or subset type.  They are introduced with the word C<where>.  In the
-following example, a constraint is used to make sure an error occurs if
-anyone ever calls a subroutine named C<abbreviate> with a string which is
-shorter than 10 characters:
-
-    sub abbreviate(Str $thing where { .chars >= 10 }) { ... }
-
-The C<Str> in the above example is also a constraint, but is usually
-referred to as a "type constraint."
-
-Note that you can also differentiate candidates in a
-L<multi-dispatch|#Multi-Dispatch> by using a different constraint:
-
-    multi sub abbreviate(Str $thing where { .chars > 10 }) {
-        "$thing.substr(0, 7)..."
-    }
-    multi sub abbreviate(Str $thing) { $thing }  # no constraint
