Hi Ilija,
Thanks for progressing with this, and making a clear case why these
syntaxes are confusing and redundant.
I presume the intent here is that the engine will generate an
E_DEPRECATED each time such a string is encountered. Do you know yet if
that will be easy to implement? I think some simple string handling is
built into the parser, so there may not be a single code path to look at.
The other question which I'm sure lots of users will have when they see
the deprecation is: How easy is it to adapt usages of the deprecated
syntax to use the non-deprecated variants? I'm guessing it's not as
simple as moving the $ sign, because as you point out the syntaxes have
different semantics; is there a general rule that users and/or tools can
use to generate correct replacements?
A final thought is that I seem to remember a previous thread (from
Nikita?) about the "$foo[bar]" syntax, which is also confusing. Maybe we
should consider deprecating that at the same time?
Overall, I'm definitely in favour of this simplification.
