Boy, was I wrong!

Old way:

C1 = smerl:new(foo),
{ok, C2} = smerl:add_func(foo, "bar() -> 1+1."),
smerl:compile(C2),
foo:bar(). % returns 2

New way:

A = 7,
C1 = smerl:new(foo),
{ok, C2} = smerl:add_func(foo, bar, fun() -> 3 + A end),
smerl:compile(C2),
foo:bar(). %% returns 10

Yup, Smerl now supports fun expressions -- even closures!
