# Limitations
|
|
|
|
The philosophy of mruby is to be a lightweight implementation of
|
|
the Ruby ISO standard. These two objectives are partially contradicting
|
|
due to the reason that Ruby is a powerful language with complex
|
|
implementation details which are difficult to implement in a lightweight
|
|
manner.
|
|
|
|
This document is collecting these limitations.
|
|
|

|
|
|

|
|
|
|
```Kernel.raise``` without arguments does not raise the current exception within
|
|
a rescue clause.
