How can i use limit function and my function ?

I want to define a function which gives me limit of (1 + 1/x)^x when x goes to infinity. However, the function must be user defined function. In other words, i want to match limit function and my function

f=@(x)exp(1)

lim = @(x) limit( (1 + 1/x)^x, x, inf)

lim(8) is not working

[Goktug Guvercin]

function O = lim(x)

O = limit( (1 + 1/x)^x, x, inf)

lim(8) is also not working

Maybe

syms x
fs = (1+1/x)^x ;
lfs = limit(fs,x,inf);
hfs = matlabFunction(lfs)

?
