862c0ef83d split the inline and closure iterators into different symbol kinds for easier discrimination between them 2014-03-06 21:57:35 +02:00

5324c9ebba iterators now return tyIter(T); 
tyIter(T) represents an "iteration yielding values of type T"

I'm planning to use that in the context of the `is` operator
supporting predicates such as `C.items is iterator` and also
in the upcoming support for higher-order inline iterators.

3f71b7f1f6 implements #766; 
expressions such as Type.field are now recognised by the compiler.
This also fixes a bug, preventing the user-defined to check for the presence of
regular fields in addition to procs

1d02f2ea53 wip type class reforms (the compiler bootstraps fine) 
* replace tfAny and tfAll with tyAnd and tyOr
* integrate matchTypeClass into typeRel
* introduce tyBuiltInTypeClass to handle types such as tuple, object, proc, etc

299cefdc98 make the current PContext accessible through TCandidate 
the goal here is to remove all the hacks from ParamTypeMatch and to handle
all type matching in typeRel (the context there is required to evaluate any static
params and to run the compilation tests of user-defined type classes)

027f30610e static params: expr[T] is now static[T] 
This introduces tyStatic and successfully bootstraps and handles
few simple test cases.  Static params within macros are no longer
treated as PNimrodNodes - they are now equivalent to constants
of the designated type.

de3b7cd413 progress towards adding negative type classes

1e26047c3b adding some provisions for writing lower-level unit tests targeting specific sub-systems of the compiler 
see sigmatch as an example.
tests are compiled only when the compiler is compiled with -d:selftest
to execute them, just run the resulting binary without arguments
