No. :)

"On Error Resume Next" depends its static context.

---^ test.vbs
Sub Test
  WScript.Echo "before raise"
  Err.Raise 1
  WScript.Echo "after raise"
End Sub

On Error Resume Next
WScript.Echo "before test"
Test
WScript.Echo "after test"
---$

D:\> cscript test.vbs
before test
before raise
after test

Oh, no! "after raise" is not printed!
To print, we have to insert "On Error Resume Next" line after
"Sub Test".

Ruby cannot simulate this behavior.
