The following `ERROR` seems to have a misleading text. Actually a `,` is missing before `:B`.  
Same for `Version 0.7.0-DEV.2276 `.  
Obviously the second colon is parsed as a binary operator.  
Wouldn’t it be a good idea to disallow binary operator `:` or binary operators in general at the start of a line?

julia> Dict(
       :A => sin(1)
       :B => sin(2)
       )
ERROR: UndefVarError: B not defined
Stacktrace:
 [1] macro expansion at ./REPL.jl:97 [inlined]

Yes, that’s the reason for been mislead. Therefore my question and suggestion.
