Comment(by NotFound):
An exception in open is only expected for exceptional conditions, like
being unable to create a handle, and in the pipe's case being unable to
fork or to launch a process, for example.
The pipe ask the operating system to do some work. That work can fail at
some later point. get_bool on FileHandle objects don't check error
conditions, just check if the object already is in error state.
Current pipe implementation just launch a shell, the shell can start
without problem even if the program you ask it to execute does not exist,
it takes some time to search the PATH and such. Waiting for stablization
or something in open or in get_bool will compromise the possible
implementations, probalbly slowing them down.
So, I don't think this is a bug, just wrong expectations.
