just joined the internals list (after being absent from php developers lists for a while) so excuse my ignorance if any topic I bring up has been discussed already. I checked the archives but couldn't find anything...
Proposal: Allow dangling commas in function call parameters.
Reasoning: We use some handy vararg tool functions and it's nice to be able to write
foo(
1,
2,
3,
);
since it's then easy to add a new parameter without having to add a comma to the previous list.
This would be symmetrical to the array() syntax. The patch for zend (php4 from cvs) would be minimal and I can't see any backwards-compatibility issues right now (patch attached).
Any opinions?
