Spotted this when using PhpStorm's documentation which incorrectly typehints an Exception - use of this as Exception could cause a TypeError if a non-Exception Throwable is returned.

Closes GH-463.
Clarify where tick events are generated, and delete the "equivalent
behavior" example which calls tick_handler() manually, because that
example isn't really suitable.

- Rather than implying that parentheses are optional, make clear
that they are never part of the syntax for these keywords.
- Don't spend so many examples on different types of string.
- Do include examples of non-string arguments.
- Add a note with additional examples of how parentheses interact.
- Don't refer to either construct as "function-like", instead use
the term "expression" consistently.
- Additional tidying to make the pages more consistent with each
other.
- Add "print" to the list of language constructs which are
documented as functions.
- Remove mention of what PHP versions below 5.4 did with short
echo tags.
In current PHP versions the Exception-class seems to allow all Throwable
values for its constructor's $previous param instead of only values of
type Exception.
Closes GH-442.
It is pretty confusing to only have a section about "Magic constants"
with the xmlid `language.constants.predefined` but to start that
section with a paragraph about predefined constants.
This was apparently added in response to a bug report against PHP
5.2 [https://bugs.php.net/bug.php?id=40775]. Testing suggests the
limitation was removed at least as long ago as 5.6, and probably
earlier.

It's the value of the called object.
Additionally, in php 7.1, it was no longer possible to reassign $this
indirectly through a reference.
Even in php 7.0, I'd think it would initially be more like a value
(that references can be created from) than
a reference, but I may be misunderstanding what this means or what $this
did in php 5 or older.
Closes GH-380.
The formal grammar for numeric strings included integers, and
floating-point numbers (decimals) with a mandatory exponent, but not
decimal numbers without exponent.
Closes GH-368
