In everyday language, humans have many ways to say the same thing. Softanza wants to capture most of them, so you can use any form without restrictions...
Unusually, there is a semantic difference that you want to emphasize by using a given form and not the other. For example:
? Q(" S♥ft anza ").RemoveSpaces()
Is the same as:
? Q(" S♥ft anza ").RemoveAllSpaces()
And they both give "S♥ftanza" as output.
But you may prefer to use the second one to make it explicit that all spaces are removed, including those in the middle, and not only those in the left and right of the string!
PS: This feature is also useful in providing you with the "Natural Coding" feature. We will present that later when we will deal with the "Practical Innovation" design goal.
