so is really going to the direction that many "official" operators will be "wysiwig" Unicode staff like «+» , and then for some slice of the comunity there will be ( TeX - like ?? ) ascii shortcuts , because we need them ( what was the length of the tread to figure out how to write and read them ) . So perl take placeholders from Mathematica , vector operations from Matlab , and greek and all other funny characters from TeX : use TeX; @\gamma = @\alpha \hyper[\sum] @\beta ; arcadi .
