Limit of a symbol to a string

[Gaurav Dhingra]

Hi,

>>> from sympy import symbols, limit
>>> x = symbols('x')
>>> a = "apple"
>>> limit(x, x, a)
      apple

I do not know the meaning of the a symbol tending to a string.
Even if it is correct then what is its use or significance.

Some functions convert strings to expressions automatically. It is not
recommended to do this, though. See
