The Dark Side of Ruby
summary
Shows concrete gotchas: Infinity is implemented via method_missing, radix conversions stop at base 36, and splat expansion produces non‑obvious arrays and hashes; demonstrates calling blocks with square brackets and curry changing when evaluation happens; explains Fixnum object_id arithmetic and why some integers are immediate, how private vs protected methods are inherited and when protected can be called on another object, and how module inclusion + super can silently change method lookup; includes code examples and worked surprises.
