If varName includes namespace qualifiers (in the array name if it refers to an array element), or if varName is unqualified (does not include the names of any containing namespaces) but no procedure is active, varName refers to a namespace variable resolved according to the rules described under NAME RESOLUTION in the namespace manual page.
If a procedure is active and varName is unqualified, then varName refers to a parameter or local variable of the procedure, unless varName was declared to resolve differently through one of the global, variable or upvar commands.
