defining empty function with escaped name in macro does not work

[mhinsch]

When I try to define an empty generic function from within a macro using an escaped name I get a 'malformed expression' error. Doing exactly the same thing but with a function with an empty argument list works.

julia> macro Bla()
       fname = :myfun
       :(function $(esc(fname)) end)
       end
@Bla (macro with 1 method)

julia> @Bla
ERROR: syntax: malformed expression

julia> macro Bla()
       fname = :myfun
       :(function $(esc(fname))() end)
       end
@Bla (macro with 1 method)

julia> @Bla
myfun (generic function with 1 method)
