Does not work in IRB

Due to the design limitation of the ruby internal API (RubyVM::AST.of), error_highlight cannot get the code snippet evaluated by Kernel#eval, etc. This means that error_highlight cannot show highlight lines for IRB.

This is a very tough issue. We need to design how to keep the eval'ed source code.
