Description Vladimir Panteleev 2019-08-13 20:26:17 UTC 
/////////////// test.d //////////////
import std.stdio;

void main()
{
    File[int] aa;
    aa.require(0, File("/dev/null"));
}
/////////////////////////////////////

/path/to/dmd.linux/dmd2/linux/bin64/../../src/druntime/import/object.d(3544): Error: `return` expression expected
test.d(6): Error: template instance `object.require!(int, File)` error instantiating

The cause is that File.opAssign returns void instead of File.
