I'm looking over PUP-2972, which is closely related to PUP-489, and is specified (but changeable, hence this email!) at https://github.com/puppetlabs/puppet-specifications/blob/master/language/expressions.md#-operator-8 and https://github.com/puppetlabs/puppet-specifications/blob/master/language/expressions.md#-operator
PUP-2972 has information about what I found by looking at modules from the forge and on github to see how += is being used right now. The purpose of this is to try to make += consistent with +, the behavior of + to be much more predictable, and -= is added by analogy with += existing. What I'd like to know is: * Do the semantics specified make sense? * The recommendation of PUP-2972 suggests just dropping += (and -=) because they are confusing. I'm reluctant to do that since it is already in use and has been around for a while. Is it useful to keep them around? The most notable change in functionality is that += won't work for string concatenation anymore, because + doesn't do string concatenation. Instead you'll need to use string interpolation ($a = "$a$b"). -- Andrew Parker [email protected] Freenode: zaphod42 Twitter: @aparker42 Software Developer *Join us at PuppetConf 2014 <http://www.puppetconf.com/>, September 22-24 in San Francisco* *Register by May 30th to take advantage of the Early Adopter discount <http://links.puppetlabs.com/puppetconf-early-adopter> **—**save $349!* -- You received this message because you are subscribed to the Google Groups "Puppet Developers" group.
