# Immutequality: Emulate Immutability With Equality Operator
This is a small "though experiment" to make `R` emulate the
difference between `=` ("is"), and `<-` ("becomes") as
distinguished e.g. in `F#`. In other words `=` makes a
"promise" that `x = 10` means that `x` won't change for
the remainder of the defining scope.
## Example
```{r}
library(immutequality)
## or, more silently and explicitely:
# import::from(immutequality, "=")
x = 10
print(x)
# Will raise an error!
x <- x*2
# This also
assign("x", 20)
# .. and this too
x = 20
```
