*** '() will be the empty list
|
|
|
|
*** bsl: current bsl - symbols + '()
|
|
*** isl: lambda + local
|
|
*** isl+: symbols, quoted and backquoted S-expressions
|
|
|
|
*** structures come with dot and update forms (where?)
|
|
|
|
*** if checked signatures are added, change libraries to export signatures
|
|
for basic things
