New feature, type check?

[N]

For functions I commonly make assumption about which field are available and 
sometimes about datatypes for parameters. It is possible to write check 
manually by using typeinfo(...) function and check which fields are available 
but maybe it would be good if it could be done automatically by interpreter.

Guess the most straight forward would be to add possibility to specify C style 
datatype in front of variable and possibility to limit range or others is in 
some cases useful.
