This package lets you create an array which will allow only one occurrence of
|
|
any value.
|
|
|
|
In other words no matter how many times you put in 42 it will keep only the
|
|
first occurrence and the rest will be dropped.
|
|
|
|
You use the module via tie and once you tied your array to this module it will
|
|
behave correctly.
|
|
|
|
Uniqueness is checked with the 'eq' operator so among other things it is case
|
|
sensitive.
|
|
|
|
As a side effect the module does not allow undef as a value in the array.
