The macro alias is good, but the way you call it is not, instead like this:
julia> eval(Expr(:macrocall, symbol("@m"), :(1+2)))
Expr
head: Symbol call
args: Array(Any,(3,))
1: Symbol +
2: Int64 1
3: Int64 2
typ: Any
Also please do submit a bug report as the crash error indicates, with as
much info as you can. even when you should get an error you shouldn't get a
segmentation fault.
