Nope. Did you try writing a little script to see if it's equivalent?

["A", "B", "C"].each do |c| &nbsp;&nbsp;&nbsp;&nbsp;class c \< StandardError &nbsp;&nbsp;&nbsp;&nbsp;end end

... doesn't work. Run it to see why.

But this does work;

["A", "B", "C"].each do |c| &nbsp;&nbsp;&nbsp;&nbsp;eval "class #{c} \< StandardError &nbsp;&nbsp;&nbsp;&nbsp;end" end

... maybe😉
