[Bug] `matches` expression does not correctly handle non-object values

[Luna-Klatzer]

Is there an existing issue for this?

• I have searched the existing issues

I am following the documentation's guide

• I have read the documentation

This issue exists in the latest version

• I am using the latest version

Current Behavior

Using the matches expression, a value is compared to a given interface, which can either result in true or false. However, using any value other than an object causes the expression to fail or return incorrect true states, due to the function being incorrectly implemented.

Expected Behavior

The matches expression should return false for those cases.

Steps To Reproduce

• Write an interface with any number of members (may be none)
• Use the matches expression with any primitive value, e.g.: 1 matches Xax

Environment

• Kipper: 0.13.0-alpha.2
• Environment: Firefox Nightly
• Operating System: Arch Linux
