+Within an interpolation, the double-quoted form may not contain
+whitespace. This does what the user expects in the common case of
+a quoted string ending with a period:
+
+ say "Foo = $foo.";
+
+If you really want to call a method with whitespace, you may work
+around this restriction with a closure interpolation:
+
+ say "Foo = {$foo."a method"}"; # OK

[Note: to help catch the mistaken use of C<< infix:<.> >> as a string
concatenation operator, Perl 6 will warn you about "useless use of
quotes" at compile time if the string inside quotes is an identifier.
