Issues with inline comparison of functions

[Matocolotoe]

Description

When comparing 2 objects returned by functions without : an error appears

Steps to Reproduce

function a() :: boolean:
	return true

function b() :: boolean:
	return false

Does work :

a() = b():
a() is b():
a() != b():
a() is not b():

Does not :

a() = b()             # Invalid brackets/variables/text in ') = b('
a() != b()            # Invalid brackets/variables/text in ') != b('
a() is b()            # Invalid brackets/variables/text in ') is b('
a() is not b()        # Invalid brackets/variables/text in ') is not b('

Storing the results into variables and then comparing them does actually work, with or without :

Expected Behavior

The condition should pass.

Errors / Screenshots

The following error appears : Invalid brackets/variables/text in ... (more info in the piece of code)

I tried, that error happens when you use "inline conditions", not normal conditions (with :)
and doesn't happen if one of the expressions is not a function
