No offence taken ;)

Agreed it does become LSL++, however i think that boundary has already been
crossed in OpenSim to a certain
extent by offering osSetDynamicTextureURL and other extension functions. The
scripts that use those are now not transferable back onto
the Linden grid as there is no possible way to replicate that functionality
there currently.

Arguably supporting more datatypes is a step further, but the accessibility
of os methods from with LSL in OpenSim leaves me thinking your argument is a
little late. To me it appears that we are supporting a one way transfer of
scripts, out of SL and into OpenSim.

I personally am happy just being able to access the additional os methods
from within the c#, javascript etc. engines and not from LSL. My thoughts
were more for enabling the same powerful extensions to those who perhaps
only know LSL.

The techncal issue here really is that for the extension methods there isn't
currently a way of saying "this extension function is only available for XX
scripting language", so we probably need to implement that.
