Is Ruby pass by reference or by value?
... Ruby is pass-by-value. No ifs. No buts. No exceptions. If you want to know whether Ruby (or any other language) is pass-by-reference or pass-by-value, just try it out: def foo(bar) bar = 'reference' end; baz = 'value'; foo(baz); puts "Ruby is pass-by-#{baz}".

Does JavaScript have the interface type (such as Java's 'interface')?

Why not infer template parameter from constructor?
...*pm;
*pm = m;
I am not sure if it would be so obvious for the parser to know what template type is the MyClass pm;
Not sure if what I said make sense but feel free to add some comment, that's an interesting question.

Valid to use (anchor tag) without href attribute?
...e named anchor format is less commonly used, as the fragment identifier is now used to specify an [id] attribute (although for backwards compatibility you can still specify [name] attributes). An <a> element without an [href] attribute is still valid.
As far as semantics and styling is concer...
