Way to get string representation of an Expression?

General Usage

As I found somewhere on them internets, you can use Base.show_unquoted to convert any Expr to a string of valid Julia code:

julia> Base.show_unquoted(stdout, :(import Woof; import Bowow))
begin
    import Woof
    #= REPL[5]:1 =#
    import Bowow
end

To convert to a string, use IOBuffer, or write to a file:

julia> buf = IOBuffer();

julia> Base.show_unquoted(buf, :(import Woof; import Bowow))

julia> String(take!(buf))
"begin\n    import Woof\n    #= REPL[11]:1 =#\n    import Bowow\nend"
