You don't need the initial parentheses, and '|' looks nicer to me than ')'. However, it's been established that '|' is not available, so I tried out your example with some of the other proposals from the thread.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>db getBlogposts</DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>` filter: [ :blogPost | blogPost data < (today - 7 days)]</DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>` filter: [ :blogPost | db coolPosts includes: item )]</DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>` collectMails</DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>` do: [ :mail | "Happy to announce ..."]</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>db getBlogposts</DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>$ filter: [ :blogPost | blogPost data < (today - 7 days)]</DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>$ filter: [ :blogPost | db coolPosts includes: item )]</DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>$ collectMails</DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>$ do: [ :mail | "Happy to announce ..."]</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>db getBlogposts</DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>;; filter: [ :blogPost | blogPost data < (today - 7 days)]</DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>;; filter: [ :blogPost | db coolPosts includes: item )]</DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>;; collectMails</DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>;; do: [ :mail | "Happy to announce ..."]</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>The backtick is perhaps the cleanest-looking alternative, and it doesn't have any conflicting associations with other Smalltalk syntax.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>I don't like '$' very much... it looks very "heavy", and it looks a lot like a character literal even though it has nothing to do with them.

Most importantly, it shares both visual and semantic similarity with the cascade operator, since both operators affect the receiver of the subsequent message.
