Is it Possible to create an entire application using just dynamic parts of C#?
<p>I am feeling rather impish about this, so please don't think I would seriously try this as I know from bitter experience the strengths of a static type checking system.</p>

<p>But, as for a concept, would it be possible to basically do C# in a completely dynamic way, throwing the static type checker to one side and saying "pah, you're so old fashioned!".</p>

<p>I have recently had great experience of IronPython and F#, but I feel truly at home in a C based language.</p>

<p>How far can one take C# on the road to dynamics? I recently wrote an XML to ExpandoObject parser and that was great, it felt like javascript prototyping. </p>

<p>How optimised is the dynamic stuff, is it as quick as some of the real Dynamic programming language environments out there such as NodeJs and CPython?</p>
