=== What steps will reproduce the problem ===

try 1

=== What is the expected behavior? ===

The code should not compile. The compiler should give a compilation error.

The syntax specified in the specification, section 6.22, requires a block inside curly braces after the try keyword. A simple expression after try is not allowed.

=== What do you see instead? ===

scala> try 1
res0: Int = 1

=== What versions of the following are you using? ===

  • Scala: 2.8.1
  • Java: 1.6.0_21
  • Operating system: Windows Vista

It's the specification which needs updating. (And also for catch, which can take any expression of the right type.)

Jason was working on a warning for "try(expr)" because it's too easy to accidentally type that when you meant "Try(expr)'
