Organic Jacy
The idea of organic Jacy is to have deeper underlying language than main and unsafe dialect.
Organic is a dialect of Jacy which does not replace but extends the functionality.
It is kind of unsafe
code but from the view of compiler stability, safety, etc.
If some feature idea sounds awkward or dangerous for the target user, but by the way is well-formed and working -- it can be added to organic dialect.
Some notes
Parser extension?
Organic Jacy does not extend parser, it does not include DSL for parser-generator whatever. Anyway, OJ includes some constructions that extend syntax, e.g. custom operators declaration.
