In the old calling scheme the exception object arrived as P5 in the
handler. This doesn't really fit into the new scheme.
I can see two ways to go:
Store the exception (or an array of unhandled exceptions) in the
interpreter and make exceptions available as:
a) e = interpinfo .INTERPINFO_EXCEPTION
b) via the get_params opcode
The latter would reflect the exception call being an internal
continuation invocation:
push_eh handler
# throw
handler: # handler:
get_params "(0)", e # .param pmc e
(Except that .param isn't allowed in arbitrary position currently)
Proposals welcome,
