D syntax improvement ideas, huh?
Make UFCS work for locally defined functions, with a pragma or
something, because it can confuse people, but it can also be
useful for state machines on ranges, and to avoid cluttering up
module namespaces.
Pass a block of code as an argument, outside the parentheses.
like foo!(bar,baz) { stuff } would be defined as template
foo(bar,baz,block stuff) { ... } or something.
(incidentally you can sort of do this already, for instance by
making a struct that completes evaluation after you call
opBinary(string op, void delegate()) if op == "|", then
makestruct(foo,bar) | { stuff })
Allow struct initializers to construct function arguments. I
mean, seriously. We already practically have support for keyword
arguments, except for this.
void foo(Something info) {...}
foo({
arg: 23,
arg2: 42,
keyword: value
});
I dunno, optional parentheses if there's just one argument? So
you could do void foo(void delegate() bar) { ... } then just foo
{ stuff } instead of foo({ stuff })
