Syntax verbosity

[titpetric]

The phpscript vm already allows fn, func and function to define a function. This makes the code less wordy on definitions.

<?php

class Test {
        function isValid() {
                echo "Test OK";
        }

        function isAdmin() {
                return false;
        }
}

The above is valid PHP syntax.

<?php

class Test {
        fn isValid() {
                echo "Test OK";
        }

        func isAdmin() {
                return false;
        }
}

The above syntax is valid phpscript syntax.

I'm filing this issue to consider omitting the function keyword in a class definition.

<?php

class Test {
        isValid() {
                echo "Test OK";
        }

        isAdmin() {
                return false;
        }
}

To control the behaviour, runner.Options should include a StrictMode flag. If true:

• only function will be accepted to match PHP function definitions,
• if/for and other statements must be parenthesised if (...)

If false:

• use fn, func or omit the keyword for class methods
• relaxed parenthesis rules for conditions and related statements
• optional / trimmed ending line semicolons
• code is incompatible with the PHP runtime ($this->name instead of array($this, "name") works...)

Considerations:

• namespaces and class autoloading are still difficult, but I may want to use them as an author to vendor code,
• call_user_func_array (and missing call_user_func) should support php array($this, "name") for a callable reference,

Out of scope / won't do:

• do we type hint a callable?
• do we type hint function arguments?
• do we type hint returns (php returns have 'array' not []T)?

The answer is probablly no, but I'd consider tweaking this syntax further in the future as opt-in.
