7 Immutable and Mutable Conversion
| (require scramble/immutable) | package: scramble-lib |
procedure
v : any/c
Returns a value like v that is shallowly immutable (see
immutable?). The argument must be a vector, string, or other type of
data with both mutable and immutable variants. (Mutable pairs are not considered
a mutable variant of pairs.)
The result is immutable, and it is not an impersonator. If v is a suitable result, it is returned as the result; that is, the result of the function might not be a fresh value.
Note that if v is impersonated, this function can raise an exception due to accessing v.
Like immutable, but returns a value that is shallowly mutable and not
an impersonator.
If fresh? is true, then the result is a new value that does not share storage (shallowly) with v.
Note that if v is impersonated, this function can raise an exception due to accessing v.
