This is as odd as it gets. In Windows command-line:

> type math.d
module math;
import std.stdio;
import core.stdc.stdio;
import std.conv;
import std.string;

string prompt = "Enter a number: ";
int input;

void main()
{
    write(prompt);
    auto result = to!int(readln().strip);

    writeln(result);
}

I run the test module via rdmd, and enter 45:
> rdmd math.d
D:\dev\code\d_code\bugs>Enter a number: 45
'45' is not recognized as an internal or external command,
operable program or batch file.

Now I thought I'm back to command line, but it appears I'm somehow still "in"
rdmd mode:
D:\dev\code\d_code\bugs>test
std.conv.ConvException: std.conv(727): Can't convert value `test' of type
const(char)[] to type int
std.conv.ConvException: std.conv(1129): Can't convert value `test' of type
const(char)[] to type int

Finally I'm back to command line
>test
'test' is not recognized as an internal or external command,
operable program or batch file.
D:\dev\code\d_code\bugs>

Using DMD, this test module works fine:
> dmd math.d
> math.exe
Enter a number: 34
34
