This is now a super off-topic digression (sorry Will!), but the trouble
with the @windows? a : b syntax is that even though it looks like a ternary
operator, it doesn't parse as a ternary operation at all:
julia> dump(:(@windows? a : b))
Expr
head: Symbol macrocall
args: Array(Any,(3,))
1: Symbol @windows
2: Symbol ?
3: Expr
head: Symbol :
args: Array(Any,(2,))
1: Symbol a
2: Symbol b
typ: Any
typ: Any
Changing it to something like @os windows ? a : b would fix this:
julia> dump(:(@os windows ? a : b))
Expr
head: Symbol macrocall
args: Array(Any,(2,))
1: Symbol @os
2: Expr
head: Symbol if
args: Array(Any,(3,))
1: Symbol windows
2: Symbol a
3: Symbol b
typ: Any
typ: Any
We could also just make the @windows macro evaluate to true or false
appropriately and make sure that the compiler is clever enough to eliminate
conditionals where the condition is a compile-time boolean value.
