See the section `do notation` in the manual for more info.
* nkMacroStmt has been removed
Macro statements are now mapped to regular nkCall nodes.
The support for additional clauses (such as else, except, of, etc)
have been restored - they will now appear as additional arguments
for the nkCall node (as nkElse, nkExcept, etc nodes)
* fixed some regressions in the `is` operator and semCompiles
unittest: the check macro will print only the non-literal part of the checked expression
tests/run: added tunittests.nim as a single central executable where unittests could be added for quicker compilation/execution of the test suite
AST-to-string conversion procs renamed to repr, treeRepr and lispRepr for better consistency
new dumpTree and dumpLisp procs for quick AST inspection of arbitrary nimrod blocks
Added: PNimrodNode.lineinfo for better error messages from macros
Added: seq.splice
For easier use from templates and macros, except stament now supports
the list of exception types to be supplied in nkBraket node (array literal).
proc parseExpr*(s: string) : expr {.magic: "ParseExprToAst".}
## Compiles the passed string to its AST representation
## Expects a single expression
proc parseStmt*(s: string) : stmt {.magic: "ParseStmtToAst".}
## Compiles the passed string to its AST representation
## Expects one or more statements
proc getAst*(macroOrTemplate: expr): expr {.magic: "ExpandMacroToAst".}
## Obtains the AST nodes returned from a macro or template invocation
## example:
## macro FooMacro() =
## var ast = getAst(BarTemplate())
Handling of the node.toYaml magic moved to the evaluation engine.
