Comment:
I'm not sure what the spec is.
Should this be rejected (as the `#-}` starts a new decl)?
{{{
foo = 'a'
{-# INLINE bar
#-}
bar = 'b'
}}}
Should this be rejected (as the `{-#` decl doesn't have the correct
indentation)?
{{{
foo = 'a'
{-# INLINE bar #-}
bar = 'b'
}}}
The `INLINE` pragma looks like a declaration, but the `SCC` pragma looks
like an expression, so how about this?:
{{{
foo = {-# SCC bar
#-} 'a'
}}}
?
Should the layout rule apply to the `LANGUAGE` pragma in any way? I assume
not, as we haven't had the `where` from the `module` line yet.
IMO, the particular bug in this ticket is that GHC thinks it is doing
implicit layout, when it shouldn't be.
