Mike, I only recall seeing the problem when called from ITL parse. The 
thought that there is some residual guff in @_ is possible, the thing 
that has me scratching my head is that the parameters are being passed 
but misdelivered by ITL parse. For example, if I pass 
thing=thing_content then it seems that $opt ends up as a literal with 
content of "thing_content" rather than a hashref with a member ->{thing} 
= "thing_content".

So when I call for $opt->{thing}, perl freaks out because I'm treating a 
literal ($opt, mistakenly containing the string "thing_content"), as the 
hashref it's supposed to be.
