April 22, 2004 Recursive function literals? | ||||
---|---|---|---|---|
| ||||
Is there any way to do it? If not, then I'm thinking, since "body" is already a keyword, you could just use that: h(function int ( int i ) { if ( i == 0 ) return i; return i + body( i-1); }); If that becomes adopted, it might also be good to encourage the use of "body" for recursions in general; it's like a big red flag that says "I recurse!", which could be handy in functions so large that you temporarily forget their names while reading them. ;-) |

Posted in reply to James Widman | I'm strange, but I like it. Then again I'm also of the opinion that there ought to be a 'pass()' statement for recursing into the superclass. A la:
class Foo {
int somefunc(int x) { ... }
}
class Bar {
override int somefunc(int x) {
if (x == SOME_SPECIAL_CASE)
// ... do stuff
pass(x); // used to be: super.somefunc(x)
}
}
I think pass() and body() would make nice siblings.
