Console: Weird behaviours and crashes when redefining action! used by console

[x8x]

executing following code in the console:

]
trim: func [a /head][
    c: func [d][]
    head
    a
]
]

returns:

red>> ]
*** Syntax error: missing [ at ]
*** Where: do
red>> trim: func [a /head][
[     c: func [d][]
[     head
[     a
[    ]
== func [a /head][c: func [d] [] head a]
red>> ]

*** Runtime Error 1: access violation
*** at: 0001FCACh

[x8x]

no crash but wierd:

  % red
--== Red 0.5.3 ==-- 
Type HELP for starting information. 

red>> ]
*** Syntax error: missing [ at ]
*** Where: do
red>> trim: does []
== func [][]
red>> ]
*** Script error: arg1 has no value
*** Where: arg1
red>> 

  % red
--== Red 0.5.3 ==-- 
Type HELP for starting information. 

red>> trim: does []
== func [][]
red>> ]
*** Script error: trim has no refinement called trim
*** Where: trim
red>> 

[x8x]

btw,

red>> source trim
Sorry, trim is a action! so no source is available

should be either
Sorry, trim is an action! so no source is available
or
Sorry, trim is a value of type action! so no source is available
or
Sorry, no source available for trim of type action!

Fixed the error message:

red>> source append
Sorry, append is an action! so no source is available
red>> source +
Sorry, + is an op! so no source is available
red>> source equal?
Sorry, equal? is a native! so no source is available

About the "weird crashes", they happen because you redefine an action! of the Red language which is used internally by the console code. You are allowed to do that, but at your own risks. ;-)

We will have a protection system for words in the future, to protect by default users to shoot themselves in the foot and increase security when loading untrusted code.
