Any way to peek at the first character of $stdin without actually
consuming it?
I tried using #rewind but get a seek error.
Thanks.
What about IO#getc and IO#ungetc.
Regards,

I assume you don't want to look at the first char as soon as it's
typed
What about IO#getc and IO#ungetc.
On versions < 1.9 these will only read bytes, regardless of $KCODE.
What's a reasonable alternative, $stdin.readline.chars.to_a[0] ?
