in thread two submit buttons in a form

I'm not sure if this is expected behavior, or a cavaet, or something else... when I do this (two submits on the same page) using the same NAME parameter, I get back from CGI with that name parameter an array, which only has one elements, that being the VALUE of the submit button that was hit. It's easy enough to check to see if what CGI returns is an array or not, but it seems odd and undocumented. The only thing that might be affecting this is that I use short phrases for the VALUEs, so the multiplicity of words might be causing this, but seems doubtful.

    The only way that I can duplicate this behavior is to request the value(s) of the parameter in list context:

    my @value = $q->param("bloption");

    Otherwise, CGI.pm returns a scalar with the value of bloption. Examining the URL of the submitted form (that contains the two submit buttons), I can see that only one value for bloption is actually being submitted: 

    http://localhost/~sutch/test/index.cgi?bloption=add
