Still I would consider an ordinary method or a lambda superior to
using eval.  I try to avoid eval whenever possible because of security
and other implications.  For me it's really only a last resort for
things that can't be done otherwise (e.g. defining methods which must
have an explicit block parameter).

Kind regards
