Supported

A small part of R6RS is supported:

• pre-defined operations: https://github.com/p0nce/scheme-d/blob/master/source/schemed/environment.d#L51
• special forms: https://github.com/p0nce/scheme-d/blob/master/source/schemed/eval.d#L47

Unsupported features

A large part of R6RS is unsupported:

• vectors (list is already implemented with D slices)

• Scheme numerical tower. Only double is provided
• char type
• \x escape sequence in strings

Bugs

• symbols have too lax a grammar, should respect Extended alphabetic characters
