    ---------
    Evaluate() functions differently in 11.5 than it did in previous versions and its killed many of my distributed plugins.

    I've written a LOT of code in coffee that allows the user to specify values inside of the names in a hierarchy, or that pulls such values along with other useful information from a standardized file format outside of my controll. As long as the number, decimal point, whitespace, or negative sign was the first part of the name, I could use evaluate to extract the number. It seems a lot of my plugins are now broken with 11.5 because evaluate now returns a "nil" if the string being evaluated contains string values that are not numbers. Is this an error, or was I just taking advantage of an old leak that got fixed with 11.5?

    For example you can quickly try this in a coffee tag, in versions 9.x to 11.027
    main(doc,op)
    {
    println(" evaluation = ", evaluate("15_globular") );
    }

    prints evaluation = 15.000000 to the console
    the exact same code in 11.5 prints "evaluation = nil" to the console

    In a much bigger problem, evaluate in 11.5 fails to ignore certain tokens. I have distributed plugins that take a string parsed from a standard format like " -0.1365" and use evaluate to return the number -0.136500, but 11.5 sees the space:negative combination and returns a nil. I now have to parse the number and will have to update all of my plugins if evaluate will continue to function like this. Please tell me its a bug that will change on the next update.

    To recap:                                           <11.025            11.5
    evaluate("     .1365")                   0.136500          0.136500
    evaluate("-.1365")                     -0.136500        -0.136500
    evaluate(" -.1365")                    -0.136500           nil
    evaluate(" -.1365_molecule")    -0.136500           nil

    I personally hope we can return to the version that does lots of parsing automatically, but if not, I need to know what the new rules are so I don't keep producing shortcut code that will become obsolete.
    Thanks,

    This is intentional, otherwise you couldn't evaluate something like this, evaluate("pi05 * 3") , because the numbers of pi05 would be evaluated as well.

    This case should work and therefore is under investigation.
