foo – generic semantics

0, fundamental concepts
0.0, reference – identifiers, static, environment.
0.1, evaluation – statements, dynamic, variation, evolution.

1, fundamental elements
1.0, list – fixed-point, static.
1.1, eval – evaluating, dynamic.
1.2, quote – evaluable, transitional.

2, static-based semantics
2.0, (…) – fixed-point.
2.1, (quote …) – evaluable.
2.2, (eval …) – evaluating.

3, dynamic-based semantics
3.0, (…) – evaluating.
3.1, (quote …) – evaluable.
3.2, (list …) – fixed-point.

4, comparison of them.
4.0, static-based is more easy to build a tree.
4.1, dynamic-based is more easy to express evaluating.
