Obtain formula text in explicit multiplication format?
In current GeoGebra 5 (and no, I won't be using 6, I find the UI unwieldy to the point of unusability), when I open properties of a formula, the formula is stored in a format that uses implied multiplication. This is incompatible with many CAS tools like (wx)Maxima, which require the use of explicit multiplication operator. This complicates copying formulas from GeoGebra to wxMaxima, which is sometimes needed when GeoGebra's CAS isn't powerful enough.
Is there a way to obtain a formula text in explicit multiplication format? If not, please consider it a feature request.
Note that this problem cannot be generally solved by an external converter, because formulas with implied multiplication are ambiguous. If types of objects represented by identifiers are not known, it is impossible to tell e.g. whether m(a+b) means "multiply m by the sum of a and b" or "call function m, passing the sum of a and b as argument".
