Future feature proposition: Context aware parser

[darkyne]

Future feature proposition:

It looks like many users believe the parser is magically aware of the context.
For example, they want x(2y+1) to be a multiplication but f(2y+1) to be an evaluation aka function f evaluted at 2y+1.
Since the parser had no easy way to guess these contexts, it was specified that a letter followed by an opening parenthesis was always interpreted as an evaluation aka "function of". If the user wants a multiplication instead, he needs to add the multiplication symbol * explicitly such as x*(2y+1) or simply change the order (2y+1)x.

An idea of improvement for the future that would allow the parser to have a better context understanding while allowing mathematical correctness would be to have the user declaring his functions before encoding the answer.
For example, if f is declared as a function, the parser would differentiate variables x and functions f and thus also dissociate multiplications and evaluations easily.

This might require a relatively big change to the plugin (modifications to the parser and a clean and easy way for the user to declare his functions in the web interface) but would probably increase usability and math correctness.

If some people are willing to work on this pluggin, I suggest this feature to be implemented.

This, of course, is just a suggestion.
