Rewriting Returning in Rails
Any insight as to why they chose to name it tap instead of returning? I much prefer returning.

The original use cae was where you have a method chain and you want to "tap into" one of the values, e.g.
foo().bar().blitz()
becomes:
foo().bar().tap { |b| puts b.inspect }.blitz()
It takes its inspiration from Unix's "tee."
