@mzlib[#:mode title contract]
|
|
|
|
This library is designed as a backwards compatible library
|
|
for old uses of contracts. It should not be used for new
|
|
libraries; use @schememodname[scheme/contract] instead.
|
|
|
|
The main differences: the function contract syntax is more
|
|
regular and function contracts now support keywords, and
|
|
@tt{union} is now @scheme[or/c].
|
|
|
|
The @schememodname[mzlib/contract] library re-exports many bindings
|
|
from @schememodname[scheme/contract]:
