OK, I think Sven is right and a cascade needs at least one message send

"self ; yourself"

doesn't work too (both parser don't accept this).

But

��

There are currently two methods in Pharo 5.0 with this

syntax:

DAPackageAnalyzerWindow class>>#onPackagesNamed:
DAPackageCycleDetectionTreeModel class>>#onPackagesNamed:

@Yuri, can you change that.

And I think we should fix RBParser.

Nicolai,

can you try with the RBParser directly? I believe Opal uses the RBParser.

RBParser parseMethod: 'createRedMorph

������ ^ (self new color:Color red); yourself'

Oh, RBParser sees it as:

self new

color: Color red;

yourself

:)

The following method compiles with Opal:

createRedMorph
������ ^ (self new color:Color red); yourself

but gives a syntax error with the old compilers parser

createRedMorph
������ ^ (self new color:Color red)End of block expected -> ; yourself

removing the parenthesis of course works for both.

Who is right ?

(for those who understand the ParseTreeSearcher syntax, how would

a search expression look, for finding code like:

���� "(some expression);yourself"
