Summary: info level 0 inside a method returns unexpected data

Initial Comment:
I frequently use [llength [info level 0]] to determine whether an optional argument was actu
ally passed to a proc or method. With Itcl 4.0b3 the result of [info level 0] has changed co
mpletely and makes this use impossible.

For example, the code below prints "namespace inscope ::myclass ::info level 0" with Itcl 4.
0b3 (tcl 8.6b1.1), while it prints "test" with 3.4 (tcl 8.5.4).

package require Itcl

itcl::class myclass {
    method test {{str ""}} {
        puts [info level 0]
    }
}

[myclass #auto] test
