/* Fluids.
|
||
|
||
Fluids are objects of a certain type that can hold one SCM value per
|
||
dynamic state. That is, modifications to this value are only visible
|
||
to code that executes with the same dynamic state as the modifying
|
||
code. When a new dynamic state is constructed, it inherits the
|
||
values from its parent. Because each thread executes with its own
|
||
dynamic state, you can use fluids for thread local storage.
