) Starting with 
Fortran, I discovered 
Tcl as a frontend several years ago and love to program with it. I work on a complex 
GUI for some number-crunching applications and needed to develop all sorts of code to improve data entry and display. Samples are:
Splines with free (non-monotonic) values of X and Y 
Cubic SplinesListboxes which can be sorted by drag-and-drop 
Sort Listboxes by Drag-and-DropUtility to transfer files and folders between different encodings
