It is possible in Pugs's Haskell backend by using the experimental,
unspecced (and will probably be changed) eval_haskell() primitive
to natively call Win32 DLLs.
Alternatively, you can write modules using the experimental,
unspecced (and will probably be changed) syntax:
module SHA1-0.0.1;
inline Haskell => '
import qualified SHA1
sha1 :: String -> String
sha1 = SHA1.sha1
';
Inline::C support is also trivial, by translating the C signatures
into Haskell FFI calls, and adding them to Pugs.External.C.
In Pugs's IMC backend, I expect the same syntax to still hold; I have
started investigating interop with Parrot/Tcl, and it does seem
feasible.
Bringing the topic back to perl6-language, I'd like to inquire
how eval and inlining other languages works. Here's some thoughts:
eval('printf("Hello!")', :language<C>);
eval(:C('printf("Hello!")'));
inline C => '...';
inline C => =<foo.c>;
If there is some consensus on this, I'd like to change Pugs's
existing `eval_perl5()` and `inline` syntax to agree with it.
