Thanks.
I forgot to add another thing that Johan had discovered: I don't know whether
this is an implementation issue but if static foreach can be seen as an
expansion of the loop body as separate scopes then the following case seems to
be related to this bug.
There can't be two nested functions even if they are in different scopes:
void main() {
{
void foo(){}
}
{
void foo(){}// <-- Error
}
}
Error: declaration foo is already defined in another scope in main

yeah, semi-known thing for static foreach: sometimes it is failing to
instantiate 2nd and more template instances. actually, not really failing, but
cannot see that templates for different iterations are really different, and
merging 'em into one.
afair, here frontend sees a template whose signature (mangled name, actually)
doesn't change between iterations, and deciding that one will be enough. ;-)
this is hard to fix without introducing some (noticable) slowdown (or, maybe,
proper `static foreach` operator).
for now, force instantiation with alias seems to be the only solution (this is
for those people who interested in workaround until this issue is somehow
fixed):
alias cc = condition!s;
... anySatisfy!(cc, AliasSeq!("b")) ...
