Lambda Abstractions Alone
Language with naming and parameters.
Do not care about record structures, classes, modules.
Can use lambda abstractions as sole foundation.
Translation technique:
define
I(I
1
:
theta
1
, I
2
:
theta
2
, ..., I
n
:
theta
n
) = U
=>
define
I = (
lambda
I
1
:
theta
1
. ((
lambda
I
2
:
theta
2
. ...(
lambda
I
n
:
theta
n
. U) ...)))
begin define
I
1
=U
1
,
define
I
2
=U
2
, ...,
define
I
n
=U
n
in
W
end
=>
(( ...(((
lambda
I
1
:
theta
1
. (
lambda
I
2
:
theta
2
. ...(
lambda
I
n
:
theta
n
. W) ...)) U
1
) U
2
) ...) U
n
)
invoke
I(V
1
, V
2
, ..., V
n
)
=>
((...((I V

) V
2
) ...) V
n
)
