- Method Detail
  - set
```
void set(Object value)
```
    Puts a value into this environment.
  - setOpt
```
default boolean setOpt(Object value)
```
    Puts a value into this environment in a way that may not succeed.
    For example, if this environment is based on the pattern (x, 2) then (1, 2) will succeed and will bind x to 1, but (3, 4) will fail.
    The default implementation calls set(java.lang.Object) and always succeeds.
