You can already define records in the shell - just not
with the record syntax.

Eshell V5.5.3  (abort with ^G)
1> rd(person, {name, age}).
person
2> Me = #person{name = ulf, age = 40}.
#person{name = ulf,age = 40}
3> Me#person.age.
40
4>

I think this is reasonably good. You should describe
this, and we can prototype extensions that would make
it even more convenient.
