Looks like one needs additional underscore: `${^_MYDEBUG} = 1;` [download] "No name that begins with ^_ will acquire a special meaning in any future version of Perl; such names may therefore be used safely in programs. $^_ itself, however, is reserved." "In particular, the special ${^_XYZ} variables are always taken to be in package main , regardless of any package declarations presently in scope."	[reply] [d/l]
