examples with literal value #4

Hello
First, thanks for this amazing library.

I'm using it in multiples tests, but would like advice on using it with some regex. For example this :

    ${output}    Run    ${command}
    Should Match Regexp    ${output}    ${expected_result}

    Examples:     tc    extra_options                   expected_result    --
            ...        2     str 200                     str (-?\\\\d+)

I'm trying to check the output of a command with a regexp, but need 4 antislash everytime I want to use a regexp antislash (\d became \\d)
same with $ and {, which are heavily present in my output.

I tryied to use """, ", and ' to escape my string but it didn't work.

Do you know if there is a way to declare a string without any interpolation by robot/robot-examples ?

Thanks
