Thank you!
This one worked fine:
> bracketedBlock : '{' statement* '}' -> ^(Block statement*) ;
Strangely it works for two statements but not for 3 - my input like this
{ echo 'foo'; echo 'bar'; echo 'tree'; }
Now produces this AST
64: Block
34: echo
92: 'foo'
34: echo
92: 'bar'
(No 'echo tree' in the AST).
This might be a higher level problem in my grammar though ... but if
something comes to mind I'd love to know any ideas why that might be.
Thanks again!
Cheers,
Simon
