wants to use the linker its own way) and I thought there might be a nice
generalization: a SwitchAction.  SwitchAction would be like the ListAction
we have today, but it would only execute one of the actions in the list,
depending on the value of a predicate (function or build variable).  The
idea would be to make the main LinkAction into a SwitchAction, and
different tools could append their linker action to the list, and (somehow)
hook into the predicate to indicate when to use theirs.  My hope was to
disentangle the linking stuff from the core of SCons with this.

If anyone's interested in picking it up, I believe I have a mostly-working
implementation of this somewhere.
