to CAL Language Discussion
Hi,
does somebody know if CAL supports something similar to Haskell's
"pattern guards" ?
I am looking for a way to let data analysts define algebraic functions
by describing cases without too much syntactic sugar.
risk income
| 0 < income < 10000 -> "very high";
| 10000 < income < 20000 -> "high";
| 20000 < income < 30000 -> "moderate";
Has somebody experience with extending the CAL language?
Is it easily possible to hook in a preprocessor, to the gem cutter
code gem editor, that rewrites a dsl to CAL?
Best Regards
George
