echo, include and a few others are language constructs because they are part
of the language itself rather than being functions in the same category as
regular functions are. This means that they are integral part of the
language, just like 'if', or any operator +, *, etc, though they look pretty
much like functions. It means that though syntactically they look as
functions and in the manual they are listed under functions, this is only to
make them easy to use, understand and locate in the documentation. That is
why certain rules for functions can be relaxed, such as requiring
parenthesis around its arguments, which are not actually needed but are
there so that they have the same look as regular functions.
