The following code:

x = [var(f'x{i}') for I in range(3)]
f = sum(x)
f.limit(x[1]=1)

gives an error:

SyntaxError: expression cannot contain assignment, perhaps you meant "=="?

If I replace x[1]=1 with x[1]==1, I get

ValueError: call the limit function like this, e.g. limit(expr, x=2).

and we go in circles. How to proceed?
