Robert and Tim, thank you for your clear explanations.
As mentioned before, I want to extend the ruby language.
Specifically, I want to twist the interpreter so that it expands
for instance w8s6ny into w[8].s[6].y.size(). Do you experts
think this can be achieved by modifying IRB's ruby code,
without diving into Ruby's C code?
Yes, easily.
You could put code like Robert's in the RubyLex#buf_input method (in
irb/ruby-lex.rb), for example, after @input.call but before @rests.concat.
Cheers,
Dave
