+Pairs are made of a key and a value, and there are two basic forms for
+constructing them: C<< key => 'value' >> and C<:key('value')>.

+=head4 Arrow pairs
+
+Arrow pairs can have an expression or an identifier on the left-hand side:
+
+    identifer => 42
+    "identifier" => 42
+    ('a' ~ 'b') => 1
+
+=head4 Adverbial pairs (colon pairs)
+
+Short forms without explicit values:
+
+    my $thing = 42;
+    :$thing                 # same as  thing => $thing
+    :thing                  # same as  thing => True
+    :!thing                 # same as  thing => False
+
+The variable form also works with other sigils, like C<:&callback> or
+C<:@elements>.
+
+Long forms with explicit values:
+
+    :thing($value)              # same as  thing => $value
+    :thing<quoted list>         # same as  thing => <quoted list>
+    :thing['some', 'values']    # same as  thing => ['some', 'values']
+    :thing{a => 'b'}            # same as  thing => { a => 'b' }
