Evaluate lambda expression:
In[1]:=
EvalLambda
[λ.[λ.[1[2]][λ.[2[1]]]][x.]]
Out[1]=
x.[x.]
​
Limit the number of sub-evaluation of the lambda expression:
In[1]:=
EvalLambda
[λ.[λ.[1[2]][λ.[2[1]]]][x.],1]
Out[1]=
λ.[1[x.]][λ.[x.[1]]]
In[2]:=
EvalLambda
[λ.[λ.[1[2]][λ.[2[1]]]][x.],2]
Out[2]=
λ.[x.[1]][x.]
In[3]:=
EvalLambda
[λ.[λ.[1[2]][λ.[2[1]]]][x.],3]
Out[3]=
x.[x.]
