NAME

lambda - Utility commands for anonymous procedures

Table Of Contents

SYNOPSIS

package require Tcl 8.5
package require lambda ?1?

::lambda arguments body ?arg...?
::[email protected] namespace arguments body ?arg...?

DESCRIPTION

This package provides two convenience commands to make the writing of anonymous procedures, i.e. lambdas more proc-like. Instead of, for example, to write

set f {::apply {{x} {
   ....
}}}

with its deep nesting of braces, or

set f [list ::apply {{x y} {
   ....
}} $value_for_x]

with a list command to insert some of the arguments of a partial application, just write

set f [lambda {x} {
   ....
}]

and

set f [lambda {x y} {
   ....
} $value_for_x]
