When you have A=xy+x from math perspective it looks like assigning a value to a variable. When You use A(x,y)=xy+x it looks like math function definition. You can look at it as if used variable assignment syntax and changed underlying semantics to the function definition syntax. I suppose, people are familiar with classic math syntax and it will be difficult to change their beliefs. But I also believe, that smartphone usage can change people habits. When function body defines the function signature, it is much easier to move around the function definition on small screen devices, define function, edit, and so on... I advice to watch promotional video for KatLang predecessor - https://www.youtube.com/watch?v=ya8beSCx1IA https://www.youtube.com/watch?v=ya8beSCx1IA It is still available on Windows Phone marketplace as IlCalculus app. Next goal is to develop Android app and I believe then it will be much easier to convince you, that implicit parameter declaration is the future feature of the clalculator.
