Re: What operator prepends?

Heh. Or maybe it is just a matter of perspective. Taking [id://kwaping]'s example above, one man's append is another man's prepend, if you don't care which variable you end up with:

$prepended_value .= $var;

Works for variables, but not for constants: `"prepended value" .= $var; # this reverse orientation of assignment is not supported in Perl` Maybe future versions of Perl will allow such reverse order (for constants), and then, maybe, also appendment operator could work also in prependment mode, but more universal seems having 2 operators: `.=` and `=.` (: this could continue in meditations :). Appendment = appending assignment, prependment = prepending assignment. :)	[reply] [d/l] [select]
