After a long search, I figured-out that there is no other way to
do it then the "work-around".  compileClient() promissed too much
flexibility.  It is not possible to pass compile options with it,
but only via the opts_rw and friends.

Reason: SOAP uses "any" on many places. It is also unpredictable whether
WSDLs contain "any" constructs.  The decoding of "any" is partially
run-time (at first use) using trick "any_element => 'ATTEMPT'". The means
that the compile options must be passed from compile-time into
run-time... and there is no way to achieve that, except via those opts_
settings (at least at the moment, without serious rewrite)

Concluding: the "feature" is incorrectly described in the documentation.
I'll repair that in the next release.

By the way: you can declare() the components which will be processed
for "any" beforehand. Then, you are able to pre-compile these pieces
before an fork().

"any" is ugly.
