Detailed Description

An expression.

The expression is broken into single operations and built recursively.

Each decomposed expression may be involve one operator from the following classes:

arithmetic: +, -, *, /,
bit-wise: ~, &, |, ^, ~&, ~|, ~^, ^~
logical: !, &&, ||
shift: <<, >>
conditional: ?/:
reduction: &, |, ^, ~&, ~|, ~^, ^~
equality: ==, !=, ===, !==
comparison: <, >, <=, >=

primary
