January 22, 2013 Some dynamic dispatch to reduce template bloat | ||||
---|---|---|---|---|
| ||||
This "Dynamic dispatch" section of the Clay language documentation shows a way to avoid some template bloat (that is common in Clay): https://github.com/jckarter/clay/wiki/Avoiding-generic-programming-pitfalls Maybe it's possible to make that syntax&code shorter and lighter. Bye, bearophile |

May be I do not get it, but this can already be done in D. There is always a trade-off between template binary bloat and performance penalty of dynamic typing and suggested approach (make a templated light interface and code most function using dynamic typing) is not that uncommon one even in C++ world.

Sometimes some sugar makes the difference from nearly never using a feature, and using it when it's useful. > There is always a trade-off between template binary bloat and performance penalty of dynamic typing Right. A flexible language allows you to chose case by case (with a default, when you don't care). Bye, bearophile |

Posted in reply to bearophile | What syntax sugar do you propose? There is hardly anything in the link that can't be done with current std.variant.Algebraic at first glance. Only stuff I can think of is some convenient way to retrieve strongly typed value from Algebraic back, but that is library update, nothing to do about language syntax. |

Maybe some tagging to denote what template arguments should be autoboxed?
The last piece of code in that page shows two saveClient() functions. Maybe only one of them is needed, and the other can be auto-generated.

So far not convincing, do not see a lot of added value for new syntax :)
Thanks for your explanations anyway.
