checking file existence on meterpreter client

[Joshua Smith <lazydj98 () gmail com>]

I'm writing a meterpreter script.  At one point I'm checking the existence
of a file on the target.
I can easily do

if client.fs.file.stat(file2find).file?
but that throws an error when the file doesn't exist (stdapi_fs_stat:
operation failed: 2)
neither client.fs.file.stat nor client.fs.file has a .exist? function like
::File.exist?(file2find) on the server side

What's the easiest way to check for file existence on the meterpreter client
side?
Do I just have to handle the error thrown, something like?

begin
     stat = client.fs.file.stat.new(file2find)
rescue
     print_status("File not found")
end

if stat.file?
     do stuff
end

Sorry if this is a dumb question
