[Swift-devel] Minor question about semantics

[Tim Armstrong]

I'm just looking at app function semantics and had a few questions about
how some things worked that weren't clear from the user manual.  There were
a few things I didn't quite get and wanted to make sure I wasn't missing
something.

Is there any difference between @x and @filename(x) in an app command
line?  E.g.

app (binaryfile bf) myproc (int i, string s="foo") {
    myapp i s @filename(bf);
}

versus

app (binaryfile bf) myproc (int i, string s="foo") {
    myapp i s @bf;
}

Also, what is the intended behaviour if you omit the @ in front of the
variable name? Is this valid? E.g.

app (binaryfile bf) myproc (int i, string s="foo") {
    myapp i s bf;
}


Cheers,
Tim
