Subject: ... building my own end-fix statements.

I believe it's possible to define my own end-fix qualifiers like "if"
and "unless" ...

Can anybody provide code examples for defining such a construct in Ruby?

For instance :

x.doSomething() when x.ready?

which would call x.ready? repeatedly until it returned a true then
would call x.doSomething()

... I know I could do

while( not x.ready? )
 sleep 0.5
wend

x.doSomething()

but I'd rather not.

even a

when( x.ready? ) { |result| x.doSomething() } would be fine I guess
... but wouldn't work because x.ready? would be precalculated before
when gets to it... so it wouldn't ever change... I basically need to
be able to pass two blocks if I were to do this ...

when( isReadyProc, bodyProc ) ... or something like that.

Any ideas ???
