Hello, this is exactly the kind of library I was probably going to rewrite for myself rather sooner than later, cool !
One question, though : if I understant it correctly, the default behaviour once you start defining a schema is for it to be "strict" rather than "loose", meaning that any extra key found in a map will be default generate an error. I find that a little bit unfortunate. What is a rationale behind being strict by default ? 2012/12/5 Alex Baranosky <alexander.barano...@gmail.com>: > Added a step-wise 'Getting Started' tutorial.
