I would like to call a function, which creates some random output (let's say a random integer) in a single expression twice. A minimal example:

Test := RandomInteger[2]
SumTest = Test + Test

Here, the both values "Test" in the second line are different. I want them to be the same, i.e. the output of the second line should be 0, 2 or 4 instead of 0, 1, 2, 3 or 4.

Easy peasy.

With[{t = Test}, t + t]
