OK another case where symmetry is broken

(continuing Re^3: Converting a list of numbers to use a range operator)

this works

  DB<159> $a=inf
 => "inf"

  DB<160> --$a
 => "inf"

  DB<161> ++$a  
 => "inf"

  DB<162> ++$a  
 => "inf"

this doesn't

  DB<156> $a=inf
 => "inf"

  DB<157> ++$a  
 => "ing"

  DB<158> ++$a  
 => "inh"

any clean way to avoid this?

I suppose any internal "numeric flag" or "dual var slot" is only set after (a clear) numeric operation...

Update

Stupid workaround proving my idea

  DB<174> $a=inf+0
 => "inf"

  DB<175> ++$a  
 => "inf"

  DB<176> ++$a  
 => "inf"

IMHO still a bug!

tested in 5.10

could someone plz test in newer versions and reply?

 perl -e '$a=inf; print ++$a,"\n"'
ing
