Overview
The basic container class. This object behaves almost identically to a normal array except at initialization time. Note that its name is ‘AST::ASTArray’, rather than plain ‘AST::Array’; I had too many bugs when it was just ‘AST::Array’, because things like ‘object.is_a?(Array)’ never behaved as I expected.
