[v $0-myvalue] = associate the symbol "$0-myvalue" with a float value
[expr $0-myvalue] = subtract the float value associated with the symbol
"myvalue" from $0
Therefore, [expr] should always return the value of $0 (unless you're assigning
a value to "myvalue" somewhere)
[expr]'s parser seems only to recognize an atom as a symbol when the first
character is not a number, so try the following workarounds:
[expr _$0myvalue]
[expr myvalue$0]
Both are ugly. If using tables you can avoid this mess by using an $s variable.
