1995-07-03 clasohm 1995-07-03 added cargs for curried function application
1995-04-22 nipkow 1995-04-22 I have modified the grammar for idts (sequences of identifiers with optional type annotations). idts are generally used as in abstractions, be it lambda-abstraction or quantifiers. It now has roughly the form idts = pttrn* pttrn = idt where pttrn is a new nonterminal (type) not used anywhere else. This means that the Pure syntax for idts is in fact unchanged. The point is that the new nontermianl pttrn allows later extensions of this syntax. (See, for example, HOL/Prod.thy). The name idts is not quite accurate any longer and may become downright confusing once pttrn has been extended. Something should be done about this, in particular wrt to the manual.
