Hello,
How to check if object's property is read-only or how to get the list of all the writable properties in any other way than trying to write it?

You can obtain that information from a metaclass object for the class,

In this case, it would look something like this:
>> meta=?myclass; pmeta=meta.PropertyList;
>> pmeta
pmeta =
2×1 property array with properties:
Name
Description
DetailedDescription
GetAccess
SetAccess
Dependent
Constant
Abstract
Transient
Hidden
GetObservable
SetObservable
AbortSet
NonCopyable
GetMethod
SetMethod
HasDefault
DefaultValue
Validation

>> pmeta.SetAccess
ans =
'public'
ans =
'public'
