Hi,
When trying to compile a package named 9pH, I get the following error:
{{{
/usr/bin/ghc -O -package-name 9pH-0.1 --make -XOverloadedStrings
-XPatternGuards -XTemplateHaskell Network.GpH.Protocol.Derive
[1 of 1] Compiling Network.GpH.Protocol.Derive (
Network/GpH/Protocol/Derive.hs, Network/GpH/Protocol/Derive.o )

}}}
It turns out that if I remove '-package-name 9pH-0.1' from the command
line, or change the package name, then the compilation completes without
error.
It seems that either:
1. Package names starting with numeric characters should be banned. In
which case it should be
clearly documented in the user's guide and/or in the cabal manual and
the compiler should
check this early on in the compilation.
2. Package names starting with a numeric character should be allowed. In
which case package
names should be mangled appropriately to avoid having the assembler
complain.
In my view option 2 would be preferable.
Many thanks,
Mathieu
