Description

In MRI, procs have properties _line_ and _file_. The method call

lambda {}._line_

succeeds. In JRuby, this call fails with

NoMethodError: undefined method `_line_' for #<Proc:...

The linenumber is available in the class, as it is shown in inspect:

"#<Proc:0x56f449b8@(irb):3>"

I've browsed through the sources a bit, but didn't see where it was appended.

Rubinius doesn't implement _line_ either BTW.

I don't see these in MRI in 1.8.7 or 1.9.2? In source or from the command-line? Does maybe a library you use add these somehow?

Ah, we've always used Ruby Enterprise Edition and I've come to equate it to 'MRI', but in this case there is a difference. It seems these methods are specific to Ruby Enterprise. Sorry for the unnecessary issue; close as 'Not a Bug'?

I am marking as not a bug based on this being an implementation-specific feature of REE.
