Hi,
Mightn't it be (is this English by the way? :-) a good idea to use

compilers that are not in the main tree?
If people agree that it's a good idea I would like to submit the

Hi,
Before reporting this as a bug I would like to know if it is not my
shallow understanding of Parrot... :-)
I set an exception handler, then call a subroutine and within that
subroutine an exception is triggered (because of a find_lex of a
non-existing lexical). The exception is handled but

I like the idea of (1), but I'm used to C. It seems quite clean if the
top level subroutine just returns to its caller, which happens to be

When I install and use an exception handler for the second time Parrot

because when I uncomment the second newsub it works...
Is this a behaviour of the hidden invoke (of the exception handler) that

Hi,
I am writing a parrot compiler back-end for my very own computer language

this purely for its therapeutical value :-)
Parrot is currently far from finished. A lot of things work really well
but in other corners work is
Hi,
The long story short:
* EXCEPTION_LEX_NOT_FOUND is not picked up correctly from the include file
* The return continuation of the exception does not save registers,
since $P1 (mapped to P16 by imcc) is messed up by $P2 (also mapped to
P16).
* I would really like the name of the missing
There are a number of ops that could fail. Examples are find_lex but
also the various load and lookup ops. Options for handling failure are:
- Abort parrot
- Throw an exception
- Return a default (null) value
I think it is hard for the parrot designers to decide what language
implementors want

Not global. Or, if it is global, it needs to be dynamically scoped
since you could possibly have different modules implemented in
different languages.

Currently find_lex does *not* throw an exception. Inside
