substitution in try-catch expression

[yuyichao]

Using substitution in try-catch expression does not produce expected result

julia> a = :a
:a

julia> ex = :(try
       catch $a
       end)
:(try 
    catch 
        a
    end)

julia> ex = :(try
       catch a
       end)
:(try 
    catch a
    end)

Notice in the first case a is in the catch block while in the second case a is the variable to store the exception.

Other new line sensitive structure like let doesn't have this issue though.

julia> a = :a
:a

julia> ex = :(let $a = 1
       end)
:(let a = 1
    end)

julia> ex = :(let
       $a = 1
       end)
:(let  # line 2:
        a = 1
    end)
