Sky I work in both PHP and Go concurrently; 12 years and 1 year, respectively.
And I really, really, really wish the PHP team would listen to the language criticisms of people who program in Go and related languages. Things like being able to recover from 100% of errors, making ArrayObject() 100% compatible with PHP arrays and more. We could do so much with PHP if they would just throw us a few crumbs...
I could go on. And on. But out of courtesy to Alejandro I won't. :-)
