You might be missing the fact that when I call a function as a function, and not a method, it doesn't suggest any imports.

This problem doesn't happen with writeln:

void main()
{
    writeln("hello, world");
}

Error: writeln is not defined, perhaps import std.stdio; is needed?

I expect the compiler to suggest an import of std.conv when I use `to` in the *same way*.

I don't have any idea what you mean. You mean, the feature to suggest imports is useless? There's no way to fix it?

Here's a full bug report: https://issues.dlang.org/show_bug.cgi?id=21308

It's stepping on a ripple in a carpet. It doesn't flatten the carpet, it just shifts the ripple to another spot.

I read that Google customizes searches to the individual based on their past behavior. So what other people see when they search is not what you're likely to see, especially if Google knows you hang out on dlang.org.

I don't use Google for anything but it comes up first for me. Anyone using the search bar in the upper right of this page will have it as the first result. It's the first result on Bing. It's the fifth result on DDG.

Just open a new anonymous window to get non-personalized searches.

Walter, there's a bug in the compiler code that suggests an import for a symbol such that in certain cases when you use the symbol and that symbol isn't defined, it doesn't suggest the import. It doesn't suggest anything. It doesn't shift to another spot. If you fix the bug, it should always suggest the import.

I don't agree that suggesting a global function for a .property is the most useful hint.

It's clearly a subjective opinion. But eventually there will be another "bug" report about why the hint is obviously wrong. That's par for the course whenever the compiler makes a suggestion about a fix.

It seems you missed one crucial point here: the suggestion to import std.conv
*does* happen when invoked as 1.to!string, but *not* when invoked as to!string(1). It's already doing what you say is not the most useful hint, and failing to give a hint when to!string is invoked as a function call.

unittest {
    // template instance to!string template to is not defined
    auto x = to!string(1);

    // no property to for type int, perhaps import std.conv; is needed?
    auto y = 1.to!string;
}

Correct - and it'd be likely of anyone else searching for that as well.
